MMDS Directional Filter Combiner

UBS offers a line of directional semi-adjacent and adjacent channel filter/combiners for both analog and digital MMDS system applications. The analog version consists of three resonator filter sections, while the digital ready version incorporates four. The channel filter/combiner is used to cascade the output of several transmitters into a common antenna waveguide line while providing protection to the transmitters against antenna line mismatches. The filters can be used to add transmitters to an existing network or can be configured to combine up to 16 arbitrary non-adjacent channels or up to 31 adjacent channels. The filters are constructed from lightweight aluminum for easy installation and come complete with the necessary hardware and test data.FeaturesSemi-Adjacent/Adjacent Channel ApplicationsAnalog/Digital Ready MMDS SystemsHigh Channel IsolationLow Pass Band Insertion LossEasy InstallationSpecificationsStandard Frequency2500-2686 MHz (2000-4000 MHz available)Insertion Loss <0.8 dB (semi-adjacent analog combiner)<1.0 dB (semi-adjacent digital ready combiner)<1.5 dB video carrier (adjacent combiner)<2.0 dB audio carrier (adjacent combiner)VSWR1.25:1 (transmitter port )1.10:1 (W/G input port)Channel Isolation30 dB (semi-adjacent analog combiner)45 dB (semi-adjacent digital ready combiner)Channel FormatsNTSC, PAL, SECAMConnectorsType N-Female (transmitter port)CPR340 (waveguide port)Operating Temperature10
