Abstract

The present invention relates to a frequency-mixing transmitting device, connected to a Ka-band satellite modem and comprising: a PCB board, and a local oscillation module, a filtering module, a frequency mixing module, a microstrip antenna module and a power amplifier module which are mounted on the PCB board. The frequency mixing module can upwardly convert an intermediate-frequency signal output from the modem into a high- frequency signal, the power of the signal is amplified by the power amplifier module of the next level, and finally, the signal is transmitted by the microstrip antenna module. By employing a modularized design thought, i.e., mounting various functional modules on a PCB board using the simple surface mounting technology, the frequency-mixing transmitting device avoids the processing step of lead bonding, facilitates high-band debugging of products and the process consistency of a high-band circuit, and has the advantages of low cost, miniature circuit, and high integration level.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a frequency mixing transmitting device working in the Ka band. Background technique [0002] In recent years, based on the advantages of large available bandwidth transmission capacity and market demand, the current market demand for multi-band communication satellites or full Ka-band communication satellites is increasing. According to statistics, among the more than 30 satellite operators in the world, more than 20 have launched or are currently launching the Ka satellite project. There are more than 30 civil Ka broadband satellites in operation, under construction and planned to be built. After 2014, the total bandwidth provided by the Ka satellites in orbit is about 500GHz-600GHz, historically surpassing all the C and Ku band satellites in orbit around the world. total bandwidth. Correspondingly, the ground terminal market has also achieved great development...
