Abstract

The invention relates to a multipath signal coupler comprising a multiplexer module and a tandem module, wherein both of the multiplexer module and the tandem module is connected with a radio frequency transmitting signal, the multiplexer module and the tandem module are connected by a first cable, the tandem module is further connected with a transceiver antenna through a second cable; first signals received by the multiplexer module and second signals received by the tandem module can include a radio frequency transmitting signal, a DC signal and an antenna servo control signal, third signals can include a low frequency signal, the radio frequency receiving signal and an antenna servo feedback signal, the low frequency signal, the radio frequency transmitting signal, the radio frequency receiving signal, the DC signal, the antenna servo control signal and the antenna servo feedback signal can be transmitted in the second cable in a collineation manner, and because of the signal isolation properties of the multiplexer module and the tandem module, the interference between the signals can be reduced, the number of feeders between devices can be reduced, and the complexity of the multipath signal coupler can be reduced.

Description

technical field [0001] The invention relates to the technical field of signal coupling, in particular to a multi-channel signal coupler. Background technique [0002] In traditional technology, a combiner includes a filter bank, a switch matrix unit and a three-terminal network unit. When the radio station is in the transmitting state, the electronic switch of the switch matrix unit gates the high-power bandpass filter with the same working frequency, and also makes the three-terminal network unit gate the channel with the same frequency as the radio station, so that the radio station The transmitted radio frequency signal passes through the electronic switch selected by the switch matrix unit, then passes through the corresponding high-power band-pass filter, and then is coupled to the antenna by the three-terminal network unit to be emitted. The channel of the radio receiving signal is the same channel as the transmitting, which is the inverse process of transmitting. The...
