Filters – Eiwave

Ei Wave offers a variety of Tunable Filter Products to satisfy a broad range of filtering applications. Tunable Bandpass and Bandreject filters provide the best solution for pre-tuning desired signals while rejecting interfering signals. The method of tuning can be either mechanical via a tuning knob mounted on the front of the filter, or electro-mechanical via an optional remote digital interface such as GPIB, RS-232, RS-422 or BCD.

Tunable filters can be offered to cover frequencies as low as 800KHz, or as high as 18GHz. Ei Wave offers Tunable Filters from stock, which cover many popular frequencies for applications such as military communications and wireless bands. Depending on the specific application, the tuning ranges can exceed an octave.
