Problems solved by technology

[0004] The traditional power amplifier backup ring design is mainly for small-scale backup situations, such as 3:2 (2 main power amplifiers, 1 backup power amplifier) ​​and 6:4, etc., and due to the space and layout constraints of the satellite platform, such as the Dongfanghong 4 platform A deck supports up to 14 power amplifiers, and backup power amplifiers cannot be shared in backup rings of different decks
The use efficiency of the power amplifier is reduced, which cannot meet the needs of users

Embodiment Construction

[0030] The invention utilizes the cascading mode of two power amplifier backup rings to connect the power amplifier backup rings on different decks, realizes the common use of the backup power amplifiers in the two backup rings, improves the efficiency of backup use, and improves the reliability of the transponder.

[0031] The specific steps are as follows:

[0032] 1. Determine the number of main and backup power amplifiers for different decks according to the layout of the satellite communication cabin: according to the layout space of the communication cabin, carry out backup design for the power amplifiers of different decks, such as the design of the north board of the communication cabin 8:6 (8 power amplifiers, 6 of them are the main power amplifiers) backup design, the south board 14:12 (14 power amplifiers, 12 of which are the main power amplifiers) power amplifier backup design, etc. To determine the cascading of backup rings:

[0033] 2 Use microwave R switch or T...

Abstract

A cascading method for the power amplifier backup loops of a communication satellite transponder is provided. By cascading two power amplifier backup loops, the backup loops on different decks are connected. The sharing of the backup power amplifier in the two backup loops is realized, the efficiency of backup using is improved, and the reliability of the transponder is improved.

Description

technical field [0001] The invention relates to a communication satellite transponder power amplifier backup ring cascading method, belonging to the technical field of communication satellite payloads. Background technique [0002] In the reliability design of the transponder, the receiver and power amplifier on the key channel should be considered as backup, so it is necessary to design a backup ring switch matrix composed of a certain number of microwave switches at the input and output ends of the key equipment. In order to ensure that switching can be completed under any combination of failures, it is necessary to use special microwave switches (such as T-type, R-type, etc.) in a certain arrangement and make necessary internal connections to form a switch matrix backup ring. [0003] In recent years, with the improvement of satellite platform capabilities, the number of transponder channels has jumped from a few channels to dozens of channels. For the sake of economic be...
