K&L Microwave offers a variety of Tunable Filter Products to satisfy a broad range of filtering applications.
Tunable Band pass and Band reject filters provide the best solution for pre-tuning the desired signals while rejecting the 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 800 KHz, or as high as 18GHz.
K&L Microwave offers Tunable Filters for military communications and wireless bands in GSM, CDMA, and LTE Band.
Depending on the specific application, the tuning ranges can exceed an octave.
