Abstract

The invention is applicable to the field of satellite television, and in particular relate to a four-output microwave frequency conversion circuit and a microwave frequency converter. The four-output microwave frequency conversion circuit comprises our amplifiers, two band-pass filters, a frequency mixer, four diodes and four voltage-regulator tubes, wherein a vertical polarization signal and a horizontal polarization signal transmitted by a satellite are respectively amplified in two stages by the amplifiers and then output to the band-pass filters, the band-pass filters performs frequency selection on the vertical polarization signal and horizontal polarization signal and then outputs to the frequency mixer, and the frequency mixer outputs the signals with the frequency band required by a satellite receiver after mixing the vertical polarization signal and horizontal polarization signal with local frequency. The circuit is simple in structure and saving in cost.

Description

technical field [0001] The invention belongs to the field of satellite television, and in particular relates to a four-way output microwave frequency conversion circuit and a microwave frequency converter. Background technique [0002] Microwave frequency converter is an indispensable device in satellite TV receiving system. Microwave frequency converters generally include front-end amplifier circuits, filter circuits, frequency mixer circuits, intermediate frequency amplifier circuits and power modules, which can amplify and filter the weak signals transmitted by Ku-band (10.7GHz-12.75GHz) satellites, and then communicate with the local Output the intermediate frequency signal (950MHz ~ 2150MHz) required by the satellite receiver after mixing the vibration frequency. [0003] At present, the four-channel output microwave frequency converter commonly used in the market consists of six low-noise amplifiers, four band-pass filters, two local oscillators, two resonators, four ...
