Netcom Shows Tunable RF Filters at EuMW
Netcom Incorporated demonstrated its tunable RF filter portfolio, including the Model 5725 notch filter, at European Microwave Week 2026 in London.
Updated on Nov. 4, 2026 in Semiconductors
Netcom Incorporated, an RF communication products manufacturer based in Wheeling, Illinois, showcased its tunable filter lineup at European Microwave Week, held 4-9 October 2026 in London at ExCeL. The company demonstrated the Model 5725 tunable notch filter live at its booth.
Why it matters
The showcase highlights continued demand for tunable RF filtering in communications equipment, where engineers need components that adapt across frequency ranges. Netcom, which has manufactured RF products for nearly 50 years, presented its in-house filter designs to an international engineering audience.
The Model 5725 is a digitally tunable VHF filter operating from 70 to 110 MHz with four independently controlled notches, tuned via SPI in 100 kHz steps, handling RF input up to +25 dBm from a 3.3 V supply. Its 19.1 × 47.1 × 7.6 mm surface-mount package and -40°C to +85°C operating range are manufacturer-reported, with no independent validation noted in the source.
The players
Netcom Incorporated
A Wheeling, Illinois-based manufacturer of RF communication products with nearly 50 years of industry history, known for its tunable filter designs.
The details
Netcom ran a live demonstration of the Model 5725 notch response sweeping across its tuning range. The company's portfolio spans tunable bandpass, high-pass, low-pass, and tunable notch filters, all designed and manufactured in-house.
Timeline

Tech Race
Netcom's tunable filter showcase at European Microwave Week reflects the continuing push among RF component makers to offer reconfigurable filtering that replaces fixed-frequency parts in communications hardware. The company's Model 5725 positions its VHF tunable notch against fixed-response filters still common in legacy designs.
For engineers designing communications systems, the Model 5725 offers digital, SPI-controlled notch tuning that can replace manually adjusted filter hardware. Buyers should verify specifications and availability directly with the manufacturer, as the source does not specify pricing or sampling.
The takeaway
Tunable RF filtering lets designers adjust frequency response in software rather than hardware, which can simplify product development. Engineers evaluating such components should confirm performance against their own test requirements.
