UHF Band Pass Filters

The ERI UF Series is a family of tunable UHF television mask filters available as stand-alone bandpass filters or available integrated into complete RF systems. The UF Series UHF band pass filters are tunable and exceptionally efficient available in models to accommodate 1500 watts to 40 kilowatts. Higher power requirements are addressed with constant impedance configurations employing these tunable band pass filters. Six and eight pole designs are available for any 8-VSB and COFDM applications.

ERI also manufactures very efficient dual mode UHF band pass filters available in configuration up to 14 poles. These system feature very low insertion loss and can be provided in reflective or constant impedance configurations. With forced air cooling this band pass filter type can handle up to 60 kW average power.

ERI produces a full line of reflective and constant impedance RF filter systems for ATSC, ISDB-T, DMB, DAB, and DVB-T applications. The company’s broad range of products include RF components (either coaxial and waveguide) for combiners, hybrids, diplexers, directional couplers, motorized switches, RF loads, and much more. With the ability to call on decades of previous system designs and configurations and the significant internal engineering and manufacturing expertise ERI can quickly respond to requirements whether they be broadcast, military, or scientific applications.
