Trilithic designs and manufactures Tunable Filters in Bandpass and Bandreject versions. These units are ideally suited for precision test & measurement environments.

Bandpass models in the VF series cover a frequency range from 6 to 4000 MHz with a single model covering an octave. 3 or 5 section configurations and 3 dB bandwidths of 5% are standard for most models. Units are housed in an aluminum case with high "Q" cavities.

Trilithic also designs custom automated preselector filters featuring GPIB control for switching a series of fixed filters and tuning a variable filter bank for lab environments and CATV applications.
