Abstract

The invention discloses a small-sized pulse power amplifier, which relates to the field of microwave communication and electronic equipment and aims to solve the technical problems of large size, low gain control accuracy, large stepping and the like of a conventional small-size pulse power amplifier. An input end of an n-shaped attenuator (1) is connected with an external radio-frequency signal input end while an output end thereof is connected with a first temperature compensating circuit (2), a first amplifier (3), a second temperature compensating circuit (4), one input end of a digital-control attenuator (5), a second amplifier (6), a third amplifier (7) and a fourth amplifier (8) sequentially serially, an output end of the fourth amplifier (8) outputs amplifying signals to the outside, the other output end of the fourth amplifier is connected with an input end of a detection circuit (9); an input end of a digital-control circuit (10) is connected with external frequency information and communicated with serial ports and an output end thereof is connected with the other input end of the digital-control attenuator (5).

Description

technical field [0001] The invention relates to the fields of microwave communication and electronic equipment, in particular to a small-volume pulse power amplifier. Background technique [0002] The pulse power amplifier is a key part of the communication system. In order to protect the stable operation and high working precision of the whole system, the small volume pulse power amplifier is usually required to have the characteristics of small size, high power precision, wide operating temperature range and good stability. [0003] At present, the common pulse power amplifiers on the market mainly follow the traditional design, which has the following problems and deficiencies: [0004] 1. Large size; [0005] 2. Gain control accuracy difference step is large. Contents of the invention [0006] The present invention aims to solve the technical problems of traditional pulse power amplifiers, such as large volume and large gain control precision step, to provide a smal...
