Tunable Filters - Digitally Controlled
-
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.

Servo And VFD Filters
-
Operation of PWM-driven motors – servo motors and variable frequency drives (VFD) – causes several problems in equipment, including damage to the motor’s bearings due to leakage current causing electrical discharge machining (EDM) and damage to motor’s insulation. PWM motors also are a major source of EMI in equipment. These motor drive systems use pulsed power to drive the motors. As we are aware, the sharp edges of the pulses inevitably include high frequency components which can couple or radiate as noise to other parts of your system and cause unreliability, communication/control problems and EMC compliance issues.
