ERI Introduces New FM Bandpass Filter

Manufacturer will bring the 940 Series to the spring NAB Show

Electronics Research Inc. will introduce a new FM bandpass filter at the NAB Show.

It said the 940 Series is a compact model with an innovative form factor and construction to provide the smallest available footprint FM bandpass filter capable of handling 5 kW average power.

The filter is a four-section single cabinet design with a footprint less than 18 by 21 inches. It includes the Invar and bellows temperature compensation used in other models of ERI’s medium- and high-power FM filter products. The filter contains a cross-coupling standard for additional isolation in combiner systems with closely spaced frequencies.

The filter also is rated to handle up to 3 kW (depending on tuning) at the output after insertion losses, convection cooled; the rating is increased to 5 kW with a forced-air cooling fan. It includes 1-5/8-inch unflanged input and output connections, and the EIA flanged version is available optionally. 

The filter can be used for intermodulation product suppression or configured as an FM channel combiner. A constant impedance configuration, also compact, is available.
