Abstract:

A new successful developed x-band solid-state power amplifier is introduced.The amplifier operates in pulse mode by taking 4 pieces of final stage power modules,each of them has output of 30 W to carry out power synthesis so as to get the peak power of more than 80 W.Its maximum pulse width is 200 μs and the maximum duty cycle is 40%.The tested result shows that no matter the output power,size or the reliability has been improved greatly.
