Modems for GEO / GSO satellites provide uninterrupted monitoring 

Modems developed by Qualcomm in collaboration with non-terrestrial network (NTN)  service provider, Skylo to provide uninterrupted remote monitoring and asset tracking. They enable low power connectivity for IoT devices across satellite and cellular networks, said Qualcomm.

The modems follow the 3GPP Release 17 standards for satellite communications on GEO / GSO (geosynchronous equatorial orbit / geostationary orbit) satellites, making connectivity available globally and providing easy device set up and orientation.

Both chipsets support the Qualcomm Aware platform, which provides real time asset tracking and device management in remote areas to support critical decision making.

Qualcomm Technologies has announced the Qualcomm 212S and the Qualcomm 9205S modem chipsets with satellite capability. They power off-grid industrial use cases that require standalone non-terrestrial network (NTN) connectivity or hybrid connectivity alongside terrestrial networks, and allow IoT enterprises, developers, ODMs and OEMs to harness real time information and insights to manage business projects.

The Qualcomm Aware platform allows companies to better monitor and track valuable assets virtually anytime and anywhere around the world. The 212S and 9205S chips advance IoT tracking and monitoring capabilities to provide connectivity and coverage even in the most remote areas, said Qualcomm. 

It is designed with ultra-low power consumption for applications in remote, fixed locations, helping promote an extended usable life. Applications include gathering telemetry and data from water and gas tanks, meters, and other infrastructure equipment. It is also suitable for utility grid monitoring, early fire detection reporting, on-shore and off-shore mining installations, and environmental management.

The Qualcomm 212S is Qualcomm Technologies’ first IoT-NTN-only modem that supports the 3GPP Release 17 standards for satellite communications. It is designed for cost efficiency and value, with only the essentials necessary for satellite communications and nothing more, added Qualcomm.

The Qualcomm 212S is also compatible with the recently announced Qualcomm QCM4490 processor to deliver low power satellite connectivity to industrial handheld devices. This important integration powers time-critical, two-way messaging capabilities and one-way payload delivery between devices and customer end points or the Qualcomm Aware cloud, all while helping promote extended usable device time.

The Qualcomm 9205S modem chipset enables IoT devices to easily connect to cellular and satellite networks for virtually gap-free coverage, and integrates GNSS to provide location data.

It is suitable for industrial applications that require always-on, hybrid terrestrial and satellite connectivity for goods and assets on the move. Applications include transoceanic shipping container tracking, agricultural equipment and livestock tracking, global fleet and freight tracking for supply chain management including for logistics partners that perform remote deliveries.

The Qualcomm 9205S uses virtually the same architecture as the Qualcomm 9205 modem, making it easy to upgrade equipment designs to include satellite connectivity and enable hybrid connectivity. The Qualcomm 9205S helps enable hub-type use cases through a highly capable applications processor and peripheral support for a wide variety of IoT applications.

Like the Qualcomm 212S, the Qualcomm 9205S adheres to 3GPP Release 17 standards for satellite communications, making it easy to establish IoT-NTN connectivity using GEO/GSO satellites and eliminates the need for orientation-specific device positioning.

The Qualcomm 212S modem will be available later this year and Qualcomm 9205S modem is available now.

0.25w InGaP HBT PAs are AEX-Q100-qualified

Linear power amplifiers (Pas) by Guerrilla RF are intended for automotive and 5G infrastructure in the 2.5 and 3.6GHz bands.

The GRF5526, GRF5526W, GRF5536 and GRF5536W have been added to the company’s InGaP HBT PA series. The complete series now covers all primary cellular bands spanning 615 to 4200MHz.

The GRF5526W and GRF5536W are the first of the GRF55xx series to be AEC-Q100-qualified for automotive applications. The full qualification is targeted to be completed by the end of the summer, with advance production quantities available now.

All four PAs are also suitable for the 5G cellular boosters / repeaters and cellular compensators / compensators associated with automotive shark fin antennas.

The new linear PAs targeting 5G wireless infrastructure applications requiring exceptional native linearity over 100MHz bandwidths and over a wide temperature range of -40 to +105 degrees C. Each can deliver up to 23dBm of output power over the entire temperature range with better than -45dBc of ACLR performance and EVM levels less one per cent – all without the aid of supplemental linearisation schemes like digital pre-distortion (DPD).

The ability to beat the -45dBc ACLR (adjacent channel leakage ratio) performance metric without DPD is critical for size, cost and power-sensitive cellular applications like home and commercial repeaters/boosters, femtocells, picocells and cable loss compensators found in automobiles.

The PAs span frequencies 2.3 to 2.7GHz and 3.3 to 4.2GHz respectively, the GRF5526 / GRF5526W and GRF5536 / GRF5536W are tuned to operate within the n7, n30, n38, n40, n41, n48, n53, n77, n88 and n90 5G new radio (NR) bands. 

Target applications are home and commercial repeaters/boosters, femtocells, and picocells, as well as cable loss compensators which are used in conjunction with automotive ‘shark fin’ antennas. In each of these use cases, the sensitivity to cost, power and size constraints prohibits the use of elaborate linearisation techniques like DPD, explained Guerrilla RF. Instead, designers must rely on the power amplifier’s native linearity to meet the stringent emissions mask requirements imposed by the latest 5G standards.

With the introduction of the GRF5526 and GRF5536 Guerrilla RF now has a complete suite of commercially available linear PAs addressing all bands targeted by our 5G and automotive customer base, said Jim Ahne, Guerrilla RF’s vice president of automotive and 5G products. “The GRF5536 variants are particularly noteworthy since they capitalise on the growing popularity of the C-band – what many in the industry hail as the most attractive spectrum for 5G applications due to its ideal blend of propagation coverage and available bandwidth,” he added.

Variants of the GRF55xx family – including the GRF5526W and GRF5536W – are being qualified for full AEC-Q100 compliance. By the end of the summer, Guerrilla RF will have introduced multiple -W variants of linear PAs.

The GRF5526, GRF5526W, GRF5536 and GRF5536W come in pin-compatible 3.0 x 3.0mm, 16-pin QFN packages. Samples and evaluation boards are available for all four components.

Apollo MxFE prepares for next-gen RF design

Aerospace and defence, instrumentation and next-generation wireless communications can use the Apollo MxFE software defined, direct RF sampling, wideband mixed signal front end platform from Analog Devices (ADI).

It enables next-generation applications such as phased array radar, electronic surveillance, test and measurement and 6G communications, explained ADI.

The growth of data intensive applications is increasing the need for wider bandwidths and more rapid processing and analysis of data for 5G, 6G, Wi-Fi 7 and Wi-Fi 8, radar, signal intelligence, and other applications at the network edge which require higher speed data conversion and processing capabilities with reduced electronic testing complexity.

Developed for application versatility and rapid customisation, the Apollo MxFE offers instantaneous bandwidths up to 10GHz while directly sampling and synthesising frequencies up to 18GHz (Ku Band). This monolithic 16nm CMOS device uses high dynamic range RF ADC and RF DAC cores with the best spurious free dynamic range and noise spectral density available on the market today, said ADI. As such, Apollo MxFE helps customers accelerate design cycles and bring new products to market faster and at lower cost, while future-proofing their product designs.

Bryan Goldstein, vice president, aerospace and defence at ADI, said: “Apollo MxFE gives design engineers the flexibility to design for . . . today, as well as an ability to enhance performance over time using simple, software-defined design changes”.

Apollo MxFE’s 4T4R product offers four 12-bit RF ADCs with a sample rate up to 20Gsamples per second, four 16-bit RF DACs with a sample rate up to 28Gsamples per second, an RF input bandwidth from DC to 18GHz (Ku Band) and an instantaneous bandwidth up to 10GHz. Apollo MxFE is believed to be the industry’s first integrated radio that is capable of directly interfacing to the emerging 6G frequency bands from 7GHz to 15GHz. 

The on-chip digital signal processing (DSP) offers a real-time FFT sniffer, a full-rate programmable FIR filter, a 128-tap complex FIR filter, fast-hopping NCOs, DDCs/DUCs, and a fractional sample rate converter. The DSP is dynamically configurable, allowing for rapid changes between narrowband and wideband profiles without taking down the JESD link. Apollo MxFE supports JESD 204B/C and a very short reach (VSR) interface.

Apollo MxFE’s 8T8R product offers eight RF ADCs with a sample rate up to 8GSPS, eight RF DACs with a sample rate up to 16GSPS, an RF input bandwidth up to 16GHz, and an instantaneous bandwidth up to 3GHz. The on-chip DSP offers similar features and functionality to the 4T4R device with double the number of digital blocks, all dynamically configurable.

Apollo MxFE is augmented by variable gain amplifiers, low noise LDO and Silent Switcher regulators, clocking and multi-chip synchronisation, along with embedded digital and software technologies including algorithms and security. 

The Apollo MxFE ecosystem includes a PLL/VCO synthesiser, the LTM4702 8A µModule regulator, a 10-channel precision synchroniser  and companion TxVGA and RxVGA solutions.

HBT power amplifiers deliver 0.5W of linear output power for 5G without DPD

The GRF55xx series of InGaP HBT power amplifiers from Guerrilla RF are the first of a new class of 0.5W linear power amplifiers which target all primary cellular bands spanning 615 to 4200MHz. Guerrilla RF also offers GRF56xx variants which double the series’ output power capabilities.

The linear power amplifiers are intended for 5G wireless infrastructure applications that require exceptional native linearity over temperature extremes of -40 to +85 degrees C. Each can deliver up to 26dBm of output power with better than -45dBc of ACLR performance and EVM (error vector magnitude) levels less than 1.2 per cent, without the aid of supplemental linearisation schemes such as digital pre-distortion (DPD).

The ability to beat the -45dBc ACLR (adjacent channel leakage ratio) performance metric without DPD is critical for size, cost and power-sensitive cellular applications, for example in home and commercial repeaters / boosters, femtocells, picocells and cable loss compensators found in automobiles, explained Guerrilla RF.

The first devices to be formally released are the GRF5607 and GRF5608. The span frequency ranges of 703 to 748MHz and 746 to 830MHz, respectively. They are tuned to operate within the n12, n14, n18, n20 and n28 5G new radio (NR) bands.

The ability to beat the -45dBc ACLR performance metric without DPD is critical for cellular applications like home and commercial repeaters/boosters, femtocells, and picocells, as well as cable loss compensators which are used in conjunction with automotive ‘shark fin’ antennas. In each of these use cases, the sensitivity to cost, power and size constraints prohibits the use of elaborate linearization techniques like DPD. Instead, designers must rely on the power amplifier’s native linearity to meet the stringent emissions mask requirements imposed by the latest 5G standards.

“By essentially doubling the output power, GRF is enabling customers to increase the range of their systems by up to 40 per cent,” said Jim Ahne, Guerrilla RF’s vice president of Automotive and 5G products. “Given that these new devices are pin-pin compatible with the previously released GRF55xx series, customers now have an easy path to upgrading the range capabilities of their existing repeater/booster and compensator platforms,” he added.

The GRF5607 and GRF5608 are supplied in pin-compatible 3.0 x 3.0mm, 16-pin QFN packages.

Samples and evaluation boards are available now for both the GRF5607 and GRF5608.
