Topside cooling creates thinner, lighter 5G radio units

Wed, Jun 07, 2023

Topside cooled RF amplifier modules have been developed by NXP Semiconductors and based on packaging designed to enable thinner and lighter radios for 5G infrastructure.

Smaller base stations can be more easily and cost-effectively installed, increasing network density, while being able to blend more discretely into their environment, said NXP. Its GaN multi-chip module series, combined with what is claimed to be the industry’s first topside cooling for RF power, helps to reduce not only the thickness and weight of the radio by more than 20 per cent, but also the carbon footprint for the manufacture and deployment of 5G base stations.

“Top-side cooling represents a significant opportunity for the wireless infrastructure industry, combining high power capabilities with advanced thermal performance to enable a smaller RF subsystem,” said Pierre Piel, vice president and general manager for radio power at NXP.

Benefits afforded by NXP’s topside cooled devices are the removal of the dedicated RF shield, use of cost-effective and streamlined PCBs and separation of thermal management from RF design. These features help networking solution providers create slimmer and lighter 5G radios for mobile network operators, while reducing their overall design cycle, NXP added.

NXP’s first topside cooled RF power module series is designed for 32T32R, 200W radios covering 3.3 to 3.8GHz. The devices combine the company’s in-house LDMOS and GaN semiconductor technologies to enable high gain and efficiency with wideband performance, delivering 31dB gain and 46 per cent efficiency over 400MHz of instantaneous bandwidth.

The A5M34TG140-TC, A5M35TG140-TC and A5M36TG140-TC modules are available today. The A5M36TG140-TC will be supported by NXP’s RapidRF reference board series.

NXP Semiconductors specialises in secure connectivity solutions for embedded applications in the automotive, industrial and IoT, mobile and communications infrastructure markets while advancing a more sustainable future. The company has over 60 years of combined experience and expertise and operates in more than 30 countries.

Anritsu extends support for Wi-Fi 7 TRX tests for wireless devices

Wed, Jun 07, 2023

Anritsu extends test capabilities for manufacturing wireless communications devices with the Universal Wireless Test Set MT8870A / MT8872A which supports Wi-Fi 7 TRX tests by software options of the WLAN 802.11be TX Measurement MX887034A and WLAN 802.11be Waveforms MV887034A.

The MT8870A / MT8872A has excellent test features for manufacturing inspection of wireless communications equipment and modules, while also supporting all prior Wi-Fi TRX test standards (IEEE 802.11b / g / a / n / ac / ax).

The MX887034A and MV887034A add test features for the latest WLAN IEEE 802.11be Wi-Fi 7 standard to the MT8870A / MT8872A test set. These software options facilitate Wi-Fi 7 TRX testing without changing the manufacturing software and production line configurations in order for customers to optimise the efficiency of their equipment investment.

Offloading mobile data to the WLAN network is important to reduce traffic congestion, said Anritsu. As smartphones, tablets and home appliances, together with automobiles and factory equipment are connecting to the network, network data traffic is likely to continue increasing but the capacity of cellular communication networks, mainly used for mobile phones, is limited.

The latest Wi-Fi 7 WLAN standard attempts to address this, using a wider channel bandwidth and higher order modulation to increase data traffic capacity. A multi-link feature improves the stability of even congested networks. Introduction of Wi-Fi 7 helps implement a more robust communications environment, which is expected to drive further demand for Wi-Fi 7 devices.

Adding MX887034A and MV887034A options is Anritsu’s efficient solution to add Wi-Fi 7 test features to the customer test environment, said the company.

The Universal Wireless Test Set MT8870A / MT8872A series is designed for developing and manufacturing various wireless communication equipment. Installing up to four test units in the main unit supports a seamless frequency band up to 7.3GHz with a 200MHz bandwidth.

Each unit measures test parameters independently in parallel, enabling the MT8870A to quickly and simultaneously evaluate multiple wireless communications devices.
