Abstract

The invention discloses a device and method for realizing combination and distribution of carrier frequency signals, comprising: an annular combiner / distributor formed by cascading three or more circulators, and a band-pass filter; wherein, two Or more than two channels of frequency transmission signals and two or more channels of frequency reception signals are connected to the ring combiner / distributor through one-to-one corresponding band-pass filters; the ring combiner / distributor is used to filter the The carrier frequency signals of each channel are combined and sent to the external signal converter, and the signal converted by the signal converter is sent to each band-pass filter corresponding to the carrier frequency receiving signal one by one; wherein, the band-pass filter The frequency band includes at least the frequency band of the service signal in the corresponding carrier frequency sending signal or carrier frequency receiving signal. Through the technical scheme provided by the invention, in a communication system in which two or more carrier frequency signals are combined / distributed, the impact of the combination / distribution of carrier frequency signals on communication capabilities is greatly reduced.

Description

technical field [0001] The invention relates to signal combination and distribution technology, in particular to a device and method for realizing carrier frequency signal combination and distribution. Background technique [0002] In the field of frequency division communication, it is often necessary to transmit two or more carrier frequency signals in a communication channel such as a microwave channel. The carrier frequency signal is composed of carrier frequency sending signal and carrier frequency receiving signal. The carrier frequency signaling mainly consists of modulated service signaling obtained by modulating the service signal at the sending side onto the carrier frequency. The frequency band for carrier frequency signaling includes a frequency band for service signaling and a guard frequency band for frequency band isolation. The carrier frequency receiving signal is the carrier frequency sending signal sent by the communication peer. The frequency band of t...
