Abstract :
A small sized, high performance linearizer has been developed. This linearizer consists of only one FET and simple matching circuits and is useful in a very broadband from 2 to 12 GHz. The linearizer has been adopted into an SSPA for the GLOBALSTAR program, and a 2 dB NPR improvement has been achieved at the 3 dB output backoff point.
