Combiner with signal strength test

Abstract

The invention relates to a combiner with a signal strength test. The combiner mainly comprises multiple paths of signal input ends, signal buffer areas, a combiner control unit, a signal transmission unit, a combined signal output end, an antenna and a power management module, wherein the multiple paths of signal input ends are connected to input ends of respective signal buffer areas respectively; output ends of the signal buffer areas are connected to the combiner control unit; the combiner control unit is connected to the signal transmission unit; the signal transmission unit is connected to the combined signal output end; the antenna and the power management module are connected with the combiner control unit; the combiner control unit comprises a master control module, a signal strength test module, a buffer output control module and a current limiting control module; the signal strength test module, the buffer output control module and the current limiting control module all are connected with the master control module; and the current limiting control module is connected with the buffer output control module. A signal strength test and selection module is added to the combiner, so that a band with the best signal can be automatically selected to output signals.

Description

technical field [0001] The invention relates to the technical field of electronic information and communication, in particular to a combiner with signal strength test. Background technique [0002] In the wireless mobile phone communication system, the main function of the combiner is to combine the input multi-band signals together and output them to the same indoor distribution system. The existing combiner only provides a bridge for combining multi-band signals, and cannot play the role of signal strength testing and selection. SUMMARY OF THE INVENTION [0003] A combiner with signal strength test, comprising a multi-channel signal input terminal, a signal buffer, a combiner control unit, a signal transmission unit, a combined signal output terminal, an antenna and a power management module; the multi-channel signal input The terminals are respectively connected to the respective signal buffer input terminals; the signal buffer output terminal is connected to the combi...
