Broadband F-type power amplifier based on ultra-compact output network

The utility model provides a broadband F-type power amplifier based on an ultra-compact output network and a design method thereof. The broadband F-type power amplifier comprises an input matching circuit, a grid bias circuit, a transistor, a drain bias circuit and an output matching circuit. Wherein the input end of the input matching network is connected with the power input end, the output endof the input matching network is connected with the grid electrode of the transistor, the grid electrode bias circuit is connected with the grid electrode in parallel, the drain electrode of the transistor is connected with the output matching circuit, the drain electrode bias circuit is connected with the drain electrode in parallel, and the output end of the output matching circuit serves as power output. Compared with the prior art, the ultra-compact broadband F-type power amplifier realized by using the single-section microstrip line realizes the same broadband and high efficiency, realizes a compact output networ
