FIELD: radio engineering; frequency-selective splitters designed for splitting different-frequency signals.
SUBSTANCE: proposed microwave diplexer has device for splitting input power into two channels made in the form of directional coupler, two low-pass band filters, and matched load. Input of one low-pass filter is connected to output of directional coupler main arm. Input of second low-pass filter is connected to output of directional coupler associated line. Output of second low-pass filter is connected to input of matched load.
EFFECT: enlarged bandwidths of microwave diplexer channels and increased total passband of subbands to several octaves.
