Design of a C-Band Satellite Communications Power Amplifier Using Two GaN HEMTs
Wolfspeed, a Cree Company, has developed an application circuit that demonstrates the ability for the CGHV1F025S to operate between 4400 MHz to 5000 MHz for satellite communication (SatCom) applications. The circuit utilizes two devices connected using a Wilkinson combiner in a balanced configuration. This application note describes the typical performance that has been achieved and what can be expected when evaluating the application fixture.
