◆ Filters MMDS spurious signals.
◆ Prevents MMDS signal leakage to UHF/VHF antenna.
◆ Power passive to MMDS block converter.
◆ DC blocked to the UHF/VHF antenna.
Applications:
◆ Separation of VHF/UHF signals and MMDS signals
◆ High isolation combining of VHF/UHF antenna and a
◆ wireless MMDS block converter.

Active Combiner

Passive Combiner

The SCS-33D and SCS-33A allows MMDS wireless signals and the local UHF/VHF off-air signals to be combined onto one cable entering the home, while preventing the MMDS aeronautical band signals from radiating backwards through the off-air antenna.
Filtering on the MMDS input eliminates spurious down converter products from interfering with the off-air channels.
The SCS-33DC provide highpass filtering for the wireless MMDS Super-band input channels.
The SCS-33A provides highpass filtering for the wireless MMDS Super-band input channels and the UHF/VHF antenna input is amplified by a low noise ampifier which provides a net gain of 4dB after high isolation combiner circuit. The directional amplifier prevents MMDS radiation from the UHF/VHF antenna.
