A design method of microstrip detector for power detection in S-band solid-state transmitter and its test results are presented. The simulation and optimization are carried out respectively with software of ADS and Ansoft Designer, then, the circuit principle diagram of the detector and simulation results are given. The complete micros- trip circuit is processed on Rogers RT/duroid 6002 substrate. The measured data is analyzed with MATLAB, and the tested results show that the designed detector has excellent linearity within frequency band range, and its voltage sensitivity is higher than 1900mv/mw, and the in -band fluctuation ratio is lower than 10%.
