Abstract

The invention discloses a high-efficiency power amplification module based on ADS load pull, and solves the problems of low efficiency and poor stability due to a fact that a continuous power amplification module designed by employing a best power impedance matching method completely depends on the self efficiency of a power amplification pipe. A signal with an input of 1900-2000MHz is successively connected to a first driving amplifier (2), a second II-shaped attenuator (3), a second driving amplifier (4) and a third II-shaped attenuator (5) via an output end of a first II-shaped attenuator (1); the output end of the third II-shaped attenuator is then successively and serially connected to a first power amplifier (6), an isolator (7), a second power amplifier (8), and a circulator (9); and at last, the signal is output via an output port of a low pass filter (10).

Description

Technical field: [0001] The present invention relates to continuous power amplifier modules. Background technique: [0002] Traditional continuous power amplifier modules usually drive the amplifier into deep saturation to maximize its efficiency. The continuous power amplifier module designed by the best power impedance matching method completely depends on the efficiency of the power amplifier tube itself, which has low efficiency and poor stability. Contents of the invention [0003] The purpose of the present invention is to provide a high-efficiency power amplifier module based on ADS load pulling with high power, high efficiency, good gain flatness and stable operation. [0004] The present invention is achieved like this: [0005] The input signal of 1900MHz~2000MHz is sequentially connected to the first drive amplifier 2, the second Π-type attenuator 3, the second drive amplifier 4, the third Π-type attenuator 5, and the third Π-type attenuator 5 through the outp...
