Designed to operate at 4.5 to 5.9 GHz from a 50 V rail, the new 70-W GaN HEMT is an ideal driver for the highest power C-band radar device on the market – the 350-W CGHV59350 GaN HEMT for 5.2 to 5.9 GHz operation, which was released in May of last year. Delivering 90 W typical POUT at 50 V, in addition to 55% drain efficiency at high 14 dB power gain, the internally matched CGHV59070 offers a general purpose broadband solution for a variety of RF and microwave applications, and is especially ideal for use in linear and compressed amplifier circuits in marine radar, weather monitoring, air and maritime vessel traffic control, and port security applications.

“First demonstrated at this year’s International Microwave Symposium, the market release of the new 70-W CGHV59070 pre-driver completes Wolfspeed’s C-Band radar lineup of pre-drivers, drivers, and output stages, enabling 1-kW, all-GaN SSPAs for C-band radar applications,” said Jim Milligan, RF and microwave director, Wolfspeed. “This latest introduction also further extends our comprehensive radar product portfolio, which helps designers achieve smaller, lighter, and higher power RF amplifiers that are critical for the development of the next-gen military, aerospace, and commercial radar applications.”

Wolfspeed’s CGHV59070 can be supplied in a ceramic/metal flange or pill package, and can be shipped individually, or alongside or installed on a test board.
