Being the simplest form of multiplexer, diplexer is a device separating two-way signals of different frequencies, and is a combination of uplink filter connecting with downlink filter in a yet-to-be-determined pattern. Distinct from that power divider separates same-frequency signal into two parts of equal power, duplexer picks up the signals of different frequencies from the public port (ANT port), and allocates the signals separately to the transmission port (TX) and receive port(RX)..
It can be used: -to improve the input selectivity of receivers, -to increase the isolation of transmitters whose respective antennas are mounted close together, and -to suppress noise sidebands and inter-modulation products.
Design and construction: The Band-pass Filter consists of high Q cavity resonators.
