Wolfspeed has announced the lineup of high-efficiency, high-gain, wide-band devices that they plan to showcase at the European Microwave Week (EuMW 2016) at ExCel London, UK (3–7 October).
They will introduce the CGHV59070 GaN HEMT for C-band radar systems. Designed to operate at 4.5 to 5.9 GHz from a 50V rail, this device is suitable as a driver for the 350W CGHV59350 GaN HEMT for 5.2 to 5.9 GHz operation (launched in May 2015). Delivering 90 Watts POUT at 50V, with a gain of 14 dB and drain efficiency of 55%, the internally matched CGHV59070 offers a general-purpose broadband solution for RF and microwave applications, and is especially suitable for use in linear and compressed amplifier circuits in marine radar, weather monitoring, air & maritime vessel traffic control, and port security applications.
First demonstrated at IMS 2016 this year, the market release of the new 70 Watt CGHV59070 pre-driver completes Wolfspeed's C-band radar lineup of pre-drivers, drivers and output stages, enabling 1 kW GaN SSPAs for C-band radar applications. The amplifier can be supplied in a ceramic/metal flange or pill package, and can be shipped individually, or alongside or installed on a test board.
This latest introduction will help 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.
Compared to conventional silicon (Si) and gallium arsenide (GaAs) devices, Wolfspeed's GaN-on-SiC RF devices deliver higher breakdown voltage, higher temperature operation, higher efficiency, higher thermal conductivity, higher power density, and wider bandwidths, all of which are critical for achieving higher performing microwave and RF products needed for emerging systems across a variety of applications. In addition to C-Band radar power amplifiers, their GaN-on-SiC RF devices also enable next-generation broadband, public safety, and ISM (industrial, scientific, and medical) amplifiers; broadcast, satellite, and tactical communications amplifiers; UAV data links; cellular infrastructure; test instrumentation; and two-way private radios.
