Micro radio frequency communication module based on RFIC

Abstract

The invention provides a micro radio frequency communication module based on RFIC, belonging to the field of aerospace application. The micro radio frequency communication module aims at solving the problems of large volume, heavy weight, high power consumption and low function density existed in the existing satellite places and a satellite communication system. A transmitting signal end of a processor is connected with the transmitting signal end of a radio frequency transmitting module; an output end of the radio frequency transmitting module is connected with an input end of a power amplifying module; the output end of the power amplifying module is connected with the input end of a circulator; a transmitting signal is radiated out by an antenna connected with the circulator; the circulator receives the signal via the antenna; the output end of the circulator is connected with the input end of a low-noise amplifier; the output end of the low-noise amplifier is connected with the input end of a radio frequency receiving module; a received signal input and output end of the radio frequency receiving module is connected with the received signal input and output end of the processor; and a direct-current voltage output end of a DC / DC converting module supplies work power for the radio frequency transmitting module, the radio frequency receiving module, the power amplifying module and the low-noise amplifier, respectively.

Description

technical field [0001] The invention relates to an RFIC-based miniature radio frequency communication module, which belongs to the field of aerospace applications. Background technique [0002] The formation flight of small satellites is a new field of research at home and abroad. Multiple small satellites fly in formation and jointly perform space missions to complete the tasks completed by a single large satellite, which can greatly improve the anti-jamming performance and anti-destruction ability of the system. . But this also puts forward new requirements for the weight, volume, functional density, power consumption and other indicators of the micro-satellite satellite-ground communication system and the inter-satellite communication system. The existing satellite-ground and inter-satellite communication systems have the problems of large volume, heavy weight, high power consumption, and low functional density. Now, in the usual satellite design, the satellite-ground co...
