The MICRO-POLE® Series of tunable filters was developed to address applications needing a small, surface mount package.  This tunable filter is varactor-based in order to minimize size and power consumption.  The varactor design also supports requirements up to 2 GHz (custom designs have been completed).  Our standard digital interface is included for ease of integration into your design and can support either serial or parallel requirements.  The product line includes several standard designs in various frequencies to support almost any applications.  Approximate performance is summarized in the Micro-Pole Series Selection Guide.
