Design of Solid-state Power Amplifierby Using Antipodal Finline-to-microstripTransition in Q-band
GE Wei;SHENG Sheng-jun;No.36 Research Institute of CETC;
An design of a solid-state power amplifier in 43 GHz~46 GHz by using antipodal finline-to-microstrip transition was presented.A low back-to-back insertion loss of less than 2 dB at the range of 43 GHz~46 GHz frequency was obtained from the transition structure. The design used gold boding wire connecting the die to themicrostrip and the structure was simulated by HFSS.A 2 Watt level die was selected for the amplifier module.The test result shows that Psat of 1.3 watt and gain of 13 dB in the frequency range of 43 GHz~46 GHz.It can be used as amplifier cell to consists high power amplifier in Q-band.
