Microwave frequency conversion circuit and microwave frequency converter

Abstract

The invention provides a microwave frequency conversion circuit and a microwave frequency converter. The circuit comprises a first radio frequency amplification module, a second radio frequency amplification module, a first frequency mixing module, a second frequency mixing module, a switching module, a first middle and low frequency amplification module, a second middle and low frequency amplification module and a power supply module. In the invention, the first frequency mixing module and the second frequency mixing module, which are highly integrated, are connected to the first radio frequency amplification module, the second radio frequency amplification module, the switching module, the first middle and low frequency amplification module, the second middle and low frequency amplification module and the power supply module respectively so as to form a dual-output circuit which can receive microwave signals emitted by two satellites. Receiving and frequency mixing processing of the microwave signals emitted by the two satellites can be realized, and according to a demand, dual-port output is performed on the selected signal emitted by any one satellite in the two satellites. The structure of the circuit is simple, there are less peripheral circuits and interferences among electronic components can be effectively reduced.

Description

technical field [0001] The embodiment of the invention belongs to the field of microwave technology, and in particular relates to a microwave frequency conversion circuit and a microwave frequency converter.
