CMD837

The CMD837 1.0 GHz to 18.0 GHz highpass / lowpass diplexer is an ideal solution when RF modulation or DC injection is essential. Each of the channels is comprised of a seven section Chebychev filter. The individual filters are diplexed to provide for a common port that passes DC to 500 MHz and 1.0 GHz to 18.0 GHz. The low frequency port allows for injection of a DC to 500 MHz bias, or control signal onto the 1.0 GHz to 18.0 GHz band. The diplexing function of the filter provides -30 dB of isolation channel to channel.
