This paper introduces the application and development status of millimeter-wave solid state power amplifier. A novel and efficient 2 × 2 fin-line millimeter-wave broadband power synthesis structure is proposed. By using three-dimensional electromagnetic field software HFSS modeling and simulation, The internal return loss is less than -20 dB and the insertion loss is less than 0.1 dB, which is in good agreement with the measured result. Based on this, a 10 W power module is developed. A low-loss 8-in-1 spatial waveguide synthesizer is designed. The measured in-band return loss is less than -20 dB and the insertion loss is less than 0.25 dB. Finally, a saturated pulse solid state power amplifier whose output power is greater than 70 W in 32-36 GHz is developed , The synthesis efficiency is above 87%, the synthesis efficiency is higher.
