Pole Zero G2 MINI-ERF™ Tunable Bandpass Filter

Pole Zero G2 MINI-ERF™ Tunable Bandpass Filter

Pole/Zero® has released a new reduced SWaP-C line of MINI-ERF™ (G2) tunable bandpass filters. These fast-tuning, low-cost, miniature, high-performance bandpass filters are commonly used in military communication and commercial applications. MN-30-520-(%BW)-S04 covers the entire tactical military tuning range of 30 MHz to 520 MHz and is currently available in either a 4% BW or 7% BW (3 dB).

MINI-ERF™ (G2) uses PIN diodes to deliver high dynamic range in a 1.75” x 2.40” x 0.387” (61 mm x 44.5 mm x 9.8 mm) package. The MINI-ERF™ (G2) series combines SMT capability with 1 Watt (input) in band and up to 2 Watts (input) out of band RF power handling, +40 dBm IIP3, low insertion loss, good selectivity, and fast tune time (15 µs typical @ 0 dBm). The digital interface format can be either SPI serial or parallel, depending on the state of the SER/PAR pin.
The MINI-ERF® requires two supply voltages. A +3.3 VDC digital supply and a high bias voltage of +100 VDC is required to bias the diodes. These supply voltages should be adequately filtered as noise present on these pins will influence the RF signal purity. The digital interface format is SPI serial or parallel depending on the state of the mode control pin. All MINI-ERF™ filters are fully pre-aligned by Pole/Zero for labor savings and ease of use.

  • Co-Site Interference in Control & Command Communication

    Command & Control (C2) platforms require multiple RF communications channels to ensure force coordination over long distances. Quite often these critical communication requirements are not met due to self-generated or cosite interference that severely degrades communication range. To ensure this does not happen to your platform, Pole/Zero® can provide a comprehensive evaluation of your platform’s communication performance level, enabling peak operation even in the most dense electromagnetic environments.

    Our mission is to assist RF communcations integrators in fielding first time successes.

  • How to specify a customized Filter design

    As an electronics design engineer working with RF signals, it is not the easiest part to select the proper filter characteristics. Communicating all the required parameters for a matching filter design and quotation is always a challenge. BSC filters helps you by providing a web-interface for several types of filters to assist you with providing complete and correct infomation to BSC so that BSC can make an initial proposal for the requested part. This can be an already existing part or a part which needs to be designed from scratch.
