查询词典 duplexer

This invention discloses a duplexer and a multiplexer of the communication system and a method to realize them on a PCB circuit, which applies a 3db bridge and a low pass filter to constitute a hopstreet duplexer without waste band channels, in which, the signals are shunted and combined by the design of the circuit structure and power distribution of the 3-db bridge and phase offset function, the band filter of the low pass filter and the reflection function of a stopband to make up of a costless duplexer in theory to merge the two channels of different frequencies and reduce loss to increase volume and working bandwidth, then a multiplexer is formed by cascading multiple duplexers.
