5G front end modules help improve 5G call quality and internet speed

Thu, Sep 15, 2022

Front end modules and pre-drivers developed by NXP are claimed to improve 5G network coverage and quality. The BTS7202 RX front end modules and BTS6403 / BTS6305 pre-drivers offer high output power, improved linearity and reduced noise.

The RX front end modules (FEM) and BTS6403 / BTS6305 pre-drivers for 5G MIMO (massive multiple-input multiple-output) going up to 20W per channel. The devices were developed and implemented in NXP’s SiGe (silicon germanium) process. They operate with modest current consumption, said NXP, designed to reduce operational costs for mobile network operators (MNOs). They are also claimed to offer improved linearity and reduced noise figure to support better 5G signal quality.

The BTS7202 RX FEMs and BTS6403/6305 pre-drivers complement NXP’s power amplifier solutions for 32T32R radios. The BTS7202 RX FEMs feature a switch capable of handling up to 20W of power leaking from transmit line-ups, reducing system complexity. The BTS6305 pre-drivers also integrate a balun to reduce costs.

As 5G networks are adopted, MNOs are increasingly leveraging 32T32R solutions to improve massive MIMO coverage in less dense urban and suburban areas. Utilising 32T32R solutions requires using higher power devices that increase the power level per channel in order to achieve the total power required to ensure strong coverage of the 5G signal.

Doeco Terpstra, vice president and general manager, smart antenna solutions, radio power, NXP, said: “Our customers recognise that higher power solution offers a way for network operators to address the power needs of 32-antenna solutions without compromising network quality.”

NXP Semiconductors specialises in secure connectivity solutions for embedded applications, in the automotive, industrial and IoT, mobile, and communication infrastructure markets.

8U universal GPU server can train in the metaverse

Thu, Sep 15, 2022

Equipped with Nvidia’s H100 / A100 GPUs, Supermicro’s Universal GPU server has been added to the company’s portfolio. It is claimed to increase AI performance, with improved thermal density resulting in lower power consumption, said the company.

This is the company’s most advanced GPU server, incorporating eight Nvidia H100 Tensor Core GPUs. The advanced airflow design means that the GPU system will allow increased inlet temperatures, which in turn reduces a data centre’s overall power usage effectiveness (PUE) while maintaining the highest performance profile, claimed Supermicro.

The 8U server is designed for diverse and computationally-intensive in data centres. It has a maximum memory capacity of 8Tbyte, enabling vast data sets to be held there, allowing faster execution of AI training or HPC applications. The architecture is designed for GPU-to-GPU communication, reducing the time needed for AI training or HPC simulations. The server also includes Nvidia GPUDirect Storage, whereby data can be directly accessed by the GPUs, to further increase efficiencies.

The 8U GPU server joins the company’s existing 4U and 5U Universal GPU systems. The Universal GPU platforms support both current and future Intel and AMD CPUs, up to 400W and above, said the company.

According to Charles Liang, president and CEO, of Supermicro. “This new server will support the next generation of CPUs and GPUs and is designed with maximum cooling capacity using the same chassis”.

The airflow design reduces fan speeds, resulting in less noise in the data centre, lower power consumption, and a reduced total cost of ownership. The system supports both AC and DC power, including support for standard OCP DC rack configurations.

Supermicro supports open standards and adheres to the open power specification for quick delivery and installation, for faster time to productivity.

Automotive test suite verifies MIPI A-PHY, says Keysight

Tue, Sep 13, 2022

An automotive serialiser / deserialiser (SerDes) receiver (Rx) compliance test has been unveiled by Keysight Technologies. It is able to verify MIPI (mobile industry processor interface) A-PHY devices and helps achieve broadscale interoperability based on the Compliance Test Specification (CTS) requirements.

It was developed in collaboration with BitifEye Digital Test Solutions and Wilder Technologies, with the support of Valens Semiconductor.

Silicon vendors are planning to implement the MIPI A-PHY long-reach physical layer interface for automotive and other surround-sensor applications, including cameras and in-vehicle infotainment (IVI) displays to meet the drive of manufacturers who are continually enhancing vehicles with autonomous functions. These functions should improve safety conditions which has led to the need for data gathered from sensors and cameras to be transmitted accurately, with precision and speed, from any silicon vendor.

Keysight’s Rx compliance test solution recreates a compliant transmitter that generates a controlled distorted signal (worst case) and analyses the impact of the distortions on the receiver’s capability to correctly sample transmitted data. It enables automotive makers and their suppliers, as well as automotive engineers and system integrators, to stress the receiver and validate its performance in the noisy and inherently harsh environment of a car.

“At Keysight, we recognise that it is critical to address the growing market demands for high-speed digital interfaces for next-generation in-vehicle networks,” said Thomas Goetzl, vice president and general manager of Keysight’s Automotive and Energy Solutions business unit.

The Rx compliance test ensures the quality of the digital transmission by measuring the receiver’s ability to recover data from an impaired input signal, with a comprehensive test framework to identify the margin at which a device under test (DUT) is working. There is also a custom fixture that couples the noise to an active link to stress the receiver and accurate and repeatable results with Keysight’s arbitrary waveform generator (AWG) to generate a variety of random and complex noise profiles.

Other features include access to pre-defined noise profiles and all relevant hardware, software and accessories in a single model number, which saves time and money, added Keysight.

There is also automatic report generation in HTML or PDF formats including margin analysis.

BitifEye Digital Test Solutions offers test software which complement Keysight´s product portfolio of integrated and automated application-specific test systems. The partnership has led to what is claimed to be the first solution that can test the receivers of automotive SerDes MIPI A-PHY data links.

“We are excited to engage with Keysight to deliver a new way for the industry to validate receiver devices utilizing MIPI A-PHY,” said Julien Henaut, chief operating officer, BitifEye Digital Test Solutions.

Keysight delivers design and validation test products for software-driven insights and analytics to bring tomorrow’s technology products to market faster across the development lifecycle, in design simulation, prototype validation, automated software testing, manufacturing analysis, and network performance optimisation and visibility in enterprise, service provider and cloud environments. Customers are in the worldwide communications and industrial ecosystems, aerospace and defence, automotive, energy, semiconductor and general electronics markets.

Radar converter raises in-cabin monitoring with 60GHz parameter

Tue, Sep 13, 2022

At European Microwave Week later this month, dSpace will unveil its DARTS HBC-7066V radar converter for validating in-cabin monitoring systems.

Automated driving from SAE level 3 upwards mandates that the driver and passengers must be permanently monitored to ensure that the driver can take the steering wheel at any time and that passengers remain in their seats. For monitoring the interior space, radar systems operating at 60GHz are the first choice, said dSpace.

The company has extended its range of radar target simulation with the DARTS HBC-7066V in order to test the radar sensors used for such tasks. The introduction of the converter makes it possible to operate any dSPace Automotive Radar Test System (DARTS) in the 60GHz V band. This also applies to DARTS in the field.

The convenient over the air (OTA) test method of the DARTS product family enables engineers to validate the entire sensor transmission channel. The small size of the converters makes them suitable for in-vehicle use, added the company.

Used in combination with various other DARTS devices, special test requirements such as distances of less than one meter, or processing bandwidths of up to 5GHz, are supported.

dSpace Automotive Radar Test Systems (DARTS) are suitable for a wide range of applications in the development process of radar sensors and vehicles equipped with these sensors. Typical applications can be found in chip design, controller testing, vehicle testing, end of line testing and vehicle homologation.

Visitors to the dSpace stand (B28) at European Microwave Week, in Milan, Italy, 25 to 30 September, will be able to see the 60GHz radar converter in a product demo.

dSpace provides simulation and validation products for developing connected, autonomous and electrically powered vehicles. The company’s range is used by automotive manufacturers and their suppliers to test the software and hardware components in new vehicles long before a new model is allowed on the road.

Engineers also rely on dSpace for aerospace and industrial automation. Its portfolio ranges from end-to-end solutions for simulation and validation to engineering and consulting services as well as training and support.

The company is headquartered in Paderborn, Germany, and has three project centres in Germany, and serves customers through regional dSpace companies in the USA, the UK, France, Japan, China, Croatia, and South Korea.
