Two-stage GaN HEMT based class-C pulsed amplifier for S-band radar applications

High performance amplifiers are always demanding in wireless communication. To amplify RF signal, power amplifier is considered as a heart source of the system. We have designed and developed a high performance two-stage pulsed class-C broadband PA for moderate range surveillance radar applications in the frequency range from 2.45 - 2.75 GHz. A common source configuration is used to deliver peak RF output power above 38 dBm. Hence, this amplifier can be used as driver amplifier for high power surveillance radar applications etc. The measured RF peak power of the amplifier is ~ 39 dBm.
