Abstract

During the last 3 years, the French MOD has supported Technologies developments or Specific MMICs design for power amplification from S-Band to Ku-Band (i.e. 18 GHz), for radar and electronic warfare applications. In this paper, we aim at presenting and analysing the results obtained on three X-Band power amplifiers using different GaAs technologies and designs to answer to the same specifications target. This comparison was conducted from a technological and measurement point of view and according to an exhaustive test plan suited to T/R module evaluation. State of the Art results are promising and able to fulfil military needs in the near future.
