Pole/Zero Releases 2nd Gen ERF-5W Bandpass Filters for UAV Communication Relay Payloads

Pole/Zero, a designer and manufacturer of RF interference mitigation products, has released a new version of their ERF-5W™ Bandpass Filter. The ERF-5W™ has been redesigned to minimize size, weight, power consumption and cost, while covering the entire military tactical radio band of 30 to 520 MHz and maintaining high in-band RF power handling (5 watts).

The ERF-5W™ is commonly used in UAV Communication Relay Payload applications. SWaP-C reductions include a new size: 4.7”x 6.8” x 1.0” (119.4 x 172.7 x 25.4 mm) and new weight: 14.08 oz. (399 g). The ERF-5W™ combines 35dB typical selectivity @ Fc ± 20%, low IL (2.5dB), and 25 μs typical tune time in a ruggedized device. Serial control is accomplished via a standard Serial Peripheral Interface (SPI)-based bus and all filters are fully pre-aligned by Pole/Zero for labor savings and ease of use.

Pole/Zero designs and manufactures a comprehensive suite of RF interference mitigation products including tunable filters, Integrated Cosite Equipment (ICE), Low Noise Amplifiers, cosite power amplifiers and other products that are ideal for solving communication problems caused by various types of RF interference.
