The result of a frequency multiplier amplifier module at Ka band is reported. The function is to escalate the centimeter wave signal to Ka Band multiplied by FET and quadrupled by PHEMT. By using power amplifier to obtain the output frequency is between 24 GHz and 30.4 GHz, the best conversion gain is 16.6dB, the output power is bigger than 50mw, and the best output power is bigger than 100mw. The frequency multiplier amplifier module at Ka band can supply good local oscillation source for the wireless communications.
