Duplexer is intended for demultiplexing of the receiving and transmitting channels, for suppression of the second and third harmonics in receiving and transmitting channels, for changeover of transmitter radiation on the antenna equivalent and for signal generation of output power switching-off of frequency up-converter at the considerable mismatch of the transmitter channel input.
