Abstract

1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION

시분할 전이중방식에 의해 적어도 두채널 이상의 신호들을 송수신하는 통신 시스템에서 송수신신호를 결합/분리하는 다중결합기에 관한 것이다.A multiplexer for combining / separating transmitted / received signals in a communication system for transmitting and receiving signals of at least two channels by a time division full-duplex method.

2. 발명이 해결하고자 하는 기술적 과제2. Technical problem to be solved by the invention

결합하는 채널수와 무관하게 한 채널에 해당하는 송신신호 전력만을 수용하며 스플리터를 사용하지 않고서도 수신신호로부터 각 채널신호를 분리한다.Regardless of the number of channels to be combined, only the transmit signal power corresponding to one channel is received, and each channel signal is separated from the received signal without using a splitter.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

각 채널의 송신신호들과 수신신호들을 각각 대역 제한하는 밴드패스필터들과, 밴드패스필터들을 통한 송신신호의 전력을 결합하여 안테나에 인가하며 안테나를 통해 수신되는 신호를 밴드패스필터들에 인가하는 정션회로와, 송신신호들을 각각 대응하는 밴드패스필터들에 인가하며 밴드패스필터들을 통한 수신신호들을 분리하는 서어큘레이터들을 구비한다.Band pass filters for band-limiting the transmission signals and the reception signals of each channel, and the power of the transmission signal through the band pass filters are combined and applied to the antenna, and the signal received through the antenna is applied to the band pass filters. And a circulator for applying the junction signals to the corresponding band pass filters and separating the received signals through the band pass filters.

4. 발명의 중요한 용도4. Important uses of the invention

FH(Frequency Hopping) 방식의 이동통신 기지국 시스템에서 송수신신호를 결합/분리하는데 이용한다.It is used for combining / separating transmitted / received signals in a mobile communication base station system of a frequency hopping (FH) method.
