K&L Microwave 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 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, BCD, ARC171, ARC234, Ethernet, USB or "Thumbwheel" panel mount.

Wide Band Filters (multi-octave)
ERF-5W™ Series (Single & Dual)
-
The new ERF-5W™ filter takes Pole/Zero’s MINI-ERF® technology to a higher level of RF power handling, with 5W (average) in-band power handling, and covering the entire military tactical radio tuning range of 30-520 MHz in one integrated package. This tunability is accomplished by the use of three poles of selectivity, multiple internal tunable filters along with high performance PIN diode RF band select switches. The tunable filters are designed to minimize size and power consumption, while maintaining high RF power handling and linearity characteristics. Serial control is accomplished via a standard Serial Peripheral Interface (SPI)-based bus.

LV Iron Core Harmonic Filters
-
Nonlinear loads such as power electronics based equipment and electric furnaces are sources of harmonic currents leading to harmonic distortion, which is one of the most important parameters for defining the power quality. Most of the commercial loads such as personal computers, photocopy machines, power supplies, and compact fluorescent lamps; and industrial loads such as AC and DC motor drives inject harmonic currents into the network that they are connected to.
