Model: DGM-18G40G-292FF-DS


PMI Model No. DGM-18G40G-292FF-DS is a Quad Phase & Amplitude Matched mmW (Milimeter Wave) Diplexer-Gain module designed to operate over the 18.0 to 40 GHz frequency range with a switched output and an integrated power divider feeding the four antenna inputs via a 20 dB coupler for ease of system set up.  The band select function not only switches bands, but also allows the amplified bands not in use to be turned off to reduce power consumption.  This model is also designed to have better than 60 dB harmonic suppression.
