NXP develops top-side cooling for RF power, shrinking 5G radios

1 min read

NXP Semiconductors has unveiled a new family of top-side cooled RF amplifier modules, based on a packaging innovation designed to enable thinner and lighter radios for 5G infrastructure.

These smaller base stations can be more easily and cost-effectively installed and are able to blend more discretely into their environment. NXP’s GaN multi-chip module series, combined with its top-side cooling solution for RF power, helps to reduce not only the thickness and weight of the radio by more than 20 percent, but the carbon footprint for the manufacture and deployment of 5G base stations as well.

“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. “This innovation delivers a solution for the deployment of more environmentally friendly base stations, while also enabling the network density needed to realise the full performance benefits of 5G.”

NXP’s top-side cooled devices are able to deliver significant design and manufacturing benefits, including the removal of the dedicated RF shield, use of cost-effective and streamlined printed circuit board, and separation of thermal management from RF design.

These features, according to NXP, WILL help networking solution providers create slimmer and lighter 5G radios for mobile network operators, while reducing their overall design cycle.

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

The A5M34TG140-TC, A5M35TG140-TC and A5M36TG140-TC products are now available.

The A5M36TG140-TC will be supported by NXP’s RapidRF reference board series.
