ERI Introduces High Efficiency UHF Band Pass Filter at NABSHOW 2017

Chandler, Indiana – April 18, 2017 – Electronics Research, Inc. will introduce a new high power UHF DTV Mask Filter at the upcoming NABSHOW 2017 in Las Vegas, Nevada at the Las Vegas Convention Center, April 24 to 27.

The UF35000 is an innovative tunable, high efficiency, waveguide UHF band pass filter. The power handling capability is 25 kW average power with convection cooling. Power handling is increased to 35 kW average power with the addition of forced air cooling and increases to 50 kW for the liquid cooled version. The filter is tunable and exceptionally efficient. The filter is constructed of lightweight silver plated aluminum. The design incorporates a unique system that allows the size of the individual cavities within the filter to be precisely adjusted to achieve resonance. This unique approach simplifies the filter construction, promotes reliability, and contributes to the low insertion loss.

In addition to the unique cavity construction all UF Series band pass filters include multiple cross couplings are provided to increase rejection of transmitter out of band emissions. Six and eight pole designs are available for 8-VSB, ISDB-T and other COFDM applications. Input and output connections are 3-1/8 inch, 4-1/16 inch or 6-1/8 inch, 50 ohm, flanged or unflanged.

ERI can provide the UF35000 as a part of a complete RF system. ERI manufactures a broad array of accessory products including directional couplers, coaxial patch panels, motorized coaxial and waveguide switches, liquid cooled RF loads, adjustable fine matchers and low pass filters. These accessory components can be assembled into systems that include support frames suitable for floor or ceiling mounted applications.
