Wide Band Filters (multi-octave)
MINI-ERF® Series
-
The MINI-POLE® Extended Range Series of tunable filters was developed to address applications needing a small, surface mount package with wide tunability. This tunability is accomplished by the use of multiple internal tunable filters along with high performance PIN diode RF band select switches all contained in one housing. The tunable filters are designed to minimize size and power consumption while maintaining high RF power handling and linearity characteristics. Parallel or serial digital interface can be selected by a mode pin for ease of integration into your design.
