Build a 5W-output, X-band PA around a plastic-packaged, surface-mount, GaN RF transistor

October 19, 2015 // By Plextek RFI
This paper describes the design of a single stage 5W X-Band GaN Power Amplifier using a low-cost SMT packaged transistor. The amplifier is optimized for the 9.3 to 9.5GHz band, has 11dB small signal gain, provides more than +37dBm output power at 3dB gain compression with a corresponding drain efficiency of greater than 55%. The design is based on a commercially available discrete 0.25μm GaN transistor.
