Problems solved by technology
[0003] At present, in order to avoid the interference of the transmitter to the receiver, usually the receiver can only realize the function of inter-frequency reception, that is, the existing receiver can only support the reception of two frequencies with a certain frequency interval (several megahertz to tens of megahertz). function, but cannot support the receiving function of two frequencies with no frequency interval or a very small frequency interval, that is, it cannot support the same-frequency dual-reception function

The embodiment of the invention discloses a frequency hopping multiplexer and a control method thereof. The frequency hopping multiplexer comprises a first channel and a second channel, wherein the first channel comprises a first duplexer, a first filter, a second filter and a second duplexer, and the second channel comprises a third filter. A first changeover switch, a second changeover switch, athird changeover switch, a fourth changeover switch and a fifth changeover switch are arranged. One of different-frequency signals sequentially passes through the first duplexer, the first filter, the second filter and the second duplexer to be output from the output end of the first channel, and the other one of the different-frequency signals passes through the third filter to be output from the output end of the second channel. One of same-frequency signals sequentially passes through the first duplexer and the first filter to be output from the output end of the first channel, and the other one of the same-frequency signals sequentially passes through the first duplexer and the second filter to be output from the output end of the second channel. Thus, the same-frequency double-receiving and different-frequency double-receiving functions of the frequency hopping multiplexer are realized.
Description
technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a frequency hopping multiplexer and a control method thereof. Background technique [0002] After receiving the electromagnetic signal received by the antenna, the receiver suppresses or filters out the signals with unnecessary frequency components in the electromagnetic signals, so as to select the signals with required frequency components in the electromagnetic signals and transmit them to the user interface. [0003] At present, in order to avoid the interference of the transmitter to the receiver, usually the receiver can only realize the function of inter-frequency reception, that is, the existing receiver can only support the reception of two frequencies with a certain frequency interval (several megahertz to tens of megahertz). function, but cannot support the receiving function of two frequencies with no frequency interval or the fr...
