Qorvo launches GaN-on-SiC PAs for military radar, communications and electronic warfare applications

Qorvo Inc of Greensboro, NC and Hillsboro, OR, USA (which provides core technologies and RF solutions for mobile, infrastructure and aerospace/defense applications) has launched three gallium nitride on silicon carbide (GaN-on-SiC) power amplifiers (PAs) optimized for use in military radar, communications and electronic warfare (EW) systems:

• TGM2635-CP – an X-band 100W MMIC amplifier operating at 7.9-11GHz for satellite communications, data links and radar applications that provides 50dBm of saturated output power, with 22.5dB of large signal gain and 35% power-added efficiency (PAE). Available in a pure copper-base bolt-down package, the TGM2635-CP offers superior thermal management for added system flexibility. 
• TGA2307-SM – a C-band 50W MMIC amplifier operating at 5-6GHz that produces more than 47dBm of saturated output power with a PAE greater than 44% and a large-signal gain greater than 20dB. Packaged in a small low-cost 6mm x 6mm plastic overmold QFN package, the TGA2307-SM provides size, weight and power (SWAP) benefits for C-band radar applications. 
• TGA2963 – a 20W wideband MMIC amplifier (in die form) operating at 6-18GHz for wideband communication platforms, radar systems, electronic warfare and test instrumentation that provides more than 43dBm saturated output power with PAE of more than 20% and a large-signal gain greater than 20dB.

"Qorvo's newest GaN PAs improve performance and reduce size and cost for defense radar, communications and EW systems by offering a combination of power, PAE and gain that is unmatched over their respective frequency bands," claims Roger Hall, general manager of Qorvo's Defense & Aerospace Products business unit. 

Qorvo is a Defense Manufacturing Electronics Agency accredited 1A Trusted Source, having completed the Defense Production Act Title III GaN-on-SiC program in 2014. The firm remains the only GaN supplier to have achieved Manufacturing Readiness Level (MRL) 9.
