Problems solved by technology

[0005] Another method that is more commonly used is to use a microwave link and add a microwave switch at its signal output end, and to achieve the purpose of signal switching by switching the microwave switch. The main problem of this method is that the equipment in deep space exploration The reliability requirements are high, and the microwave amplification link of this method is a single channel without backup, and the reliability is low

Abstract

The invention relates to a miniature solid-state power amplification device applied to deep-space exploration, and can be widely applied to various solid-state power amplification products for deep-space exploration. The solid-state power amplification device comprises a splitter, a DC / DC (direct current / direct current) power conversion circuit, a power switching circuit and a microwave amplification circuit. According to the miniature solid-state power amplification device, the DC / DC power conversion circuit is used for converting input primary power into voltage required by the microwave amplification circuit, and has the advantage of saving a larger space compared with a common mode of two paths of power; power supply to two microwave amplification links is switched through a dual-load relay; a GaAs MMIC (gallium arsenide monolithic microwave integrated circuit) chip design is adopted for integrally packaging the two microwave amplification links of the microwave amplification circuit, so that the requirements of reduction in weight and size are met; and the two microwave amplification links are backups of each other, so that the stability of the device is improved.

Description

technical field [0001] The invention relates to microwave radio frequency circuit design technology, in particular to a dual-channel microwave power amplification and switching circuit. Background technique [0002] Solid-state power amplifiers are key equipment in electronic systems such as satellite communication, radar, measurement and control, navigation, and countermeasures. They are widely used in the field of transmission and transmission due to their stable and reliable performance, convenient maintenance, and low energy consumption. [0003] Conventional solid-state power amplifiers are mainly single-channel solid-state power amplifiers, that is, one port of microwave input and one port of microwave output. One-port input and two-port output fixed products. [0004] Under normal circumstances, if two-port output fixed-amplification products want to realize two-way signal switching, a more common method is to supply power to two microwave link devices at the same ti...
