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 includes a first channel and a second channel, the first channel includes a first duplexer, a first filter, a second filter and a second duplexer, and the second channel includes a third filter. Set the first switch, the second switch, the third switch, the fourth switch and the fifth switch; one of the different frequency signals passes through the first duplexer, the first filter, and the second filter in sequence And the second duplexer is output at the output end of the first channel, and another signal is output at the output end of the second channel through the third filter; one signal in the same-frequency signal passes through the first duplexer and the first The filter is output from the output end of the first channel, and the other signal is output from the output end of the second channel through the first duplexer and the second filter in turn, realizing the same frequency double reception and different frequency of the frequency hopping multiplexer Double income function.
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...
