ERI Introduces New Compact Medium Power FM Bandpass Filter

Chandler, Indiana – March 25, 2024 – Electronics Research, Inc. will introduce an innovative new FM bandpass filter at the NAB Show in Las Vegas this April. The 940 Series FM Bandpass Filter is a new compact FM bandpass filter from ERI 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 (497 by 523 millimeters). The filter includes the same field-proven Invar and bellows temperature compensation used in all 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 is rated to handle up to 3 kW (depending on tuning)  at the output after insertion losses, convection cooled, and the rating is increased to 5 kW with a forced air cooling fan. The filter includes 1-5/8-inch unflanged input and output connections, and the EIA flanged version is optionally available. The filter can be used for intermodulation product suppression or configured as an FM channel combiner. A constant impedance configuration, which is also very compact, is also available.

Integrated Fine Matchers Added to ERI CL Series Liquid Cooled UHF RF Loads

Chandler, Indiana – April 1, 2019 – Electronics Research, Inc. introduced its new CL Series liquid cooled RF loads at NABSHOW2018. New for this year is the addition of a new model, which adds an integrated UHF Fine Matcher for all sizes available for this product family. These models also include an integrated adjustable directional coupler at the load input as well. The loads are available in 3-1/8-inch (Model CL313), 4-1/16-inch (Model CL413) or 6-1/8-inch (Model CL613) swivel flange, female inputs. This family of liquid cooled UHF coaxial loads offer a proven design for handling high RF power at low cost. The loads employ a solution of antifreeze and water as both coolant and resistive material. The power dissipated by the load heats the solution and is removed by the constant flow. The loads are 50-inches in length, including the fine matcher, to save space and are constructed from Aluminum and Stainless Steel and are very light weight, the 6-1/8-inch load weighs less than 25 pounds.

Other models in this product family include the models CL311, 3-1/8-inch; CL411, 4-1/16-inch; and CL611, 6-1/8-inch are the basic load designs. The models CL312, CL412, and CL612 include an integrated, externally terminated, adjustable directional coupler at the load input.

These products are all currently in production and availability for new orders is generally less than 30 days.
