Design and Realization of X-band 2 500 W Broadband Communication Amplifier
A design and implementation of X-band 2 500 W broadband communication power amplifier is introduced.By adopting ADS large signal model simulation method to match the impedance of power transistor and 3 dB balanced coupler to split and combine circuit,an X band 150 W final module is designed;The high power 32-way combiner is designed by using the five-stage waveguide magic T cascade and the low loss high power synthesis in X-band is realized.CST simulation software is used for simulation and optimization.The liquid-cooled case is designed by using digital simulation and structural optimization.ICEPAK software is used to design an efficient radiator,and the layout of modules in the chassis is optimized and simulated.The comprehensive control and protection circuit is adopted to improve the stability and reliability of the power amplifier.
