GaN-based amplifier provides 50+ W power from 4.4–5.0 GHz
February 12, 2020 – Geneva, Ill.: Richardson RFPD, Inc. announced today their full support for a new reference design from Wolfspeed, a Cree Company.
The CGHV1F025S-AMP4 reference design is a balanced amplifier that combines two unmatched surface mount transistors to provide over 50 W of power from 4.4 to 5.0 GHz.
The design goal of the CGHV1F025S-AMP4 was to create an application circuit for tactical radio capable of operating under a constant amplitude signal such as offset QPSK (OQPSK). It utilizes the CGHV1F025S, a 25 W RF power transistor housed in a plastic package DFN package for surface mount applications. Breakout paths are available on the board to operate a single device for applications requiring lower output power.
With measured EVM less than 3% under 6.0 dB PAPR OQPSK signal, the design meets harsh linearity requirements for troposcatter tactical radio. It is also suitable for satellite communications (SatCom) and radio links applications.
The CGHV1F025S-AMP4 reference design documentation includes a dxf file, PCB, schematic drawing and assembly drawing. A license-free copy of the files is available from Richardson RFPD.
