This paper introduces the design and realization of a L-band 1 500 W CW solid-state amplifier. The combination meth- od of dynamic impedance matching and ADS large signal model simulation is used to perform impedance match of LDMOS power tran- sistor. The microstrip balnn is used to realize divider and combiner and design an L-band 150 W CW amplifier module. The radial com- biner is used to design high-power four-channel combiner and realize L-band low-loss high-power combination. The HFSS simulation software is used to perform simulation optimization. The ICEPAK software is used to design high-efficiency radiator and perform optimi- zation simulation for module layout inside case. The full protective circuit is used to improve the reliability of high-power amplifier.
