Pole Zero Mini-Pole Filter Series

Pole Zero Mini-Pole Filter Series

The MINI-POLE Microwave Series of tunable filters was developed to address applications needing a small, surface mount package with higher power. Parallel or serial digital interface can be selected by a mode pin for ease of integration into your design and choose from a large variety of bandwidth and insertion loss combinations.

General Information

The MINI-POLE Microwave filter requires two supply voltages. A +5 VDC analog supply and a +1.65 to +5.5 VDC digital supply. An on-board +100 VDC DC-DC converter is included. If low frequency noise is of concern, then this supply can be disabled and an external +100 VDC supply may be used. This supply voltage should be adequately filtered as noise present on these pins will influence the RF signal purity.

Digital Interface Information

The digital interface format can be either SPI serial or parallel depending on the state of the mode control pin. All data input pins are universal data bus capable of 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes and selected by the VCCD supply.

  • 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.
