Abstract :
A GaN based highly integrated Solid State Power Amplifier (SSPA) is developed for S-band radar applications. The power amplifier delivers more than 1 KW within a 400 MHz bandwidth with 55 dB gain and a typical 34% PAE. The SSPA includes a negative voltage supply, sequential bias circuit, and temperature sensor circuit. Its compact and lightweight design is suitable for many radar applications.
