RF Filters

RF filters are passive devices used to allow the passage of signals within a specific, desired frequency range while blocking unwanted signals or interference outside of the desired band. Mini-Circuits offers one of the industry's widest RF filter selections including band pass filters, low pass filters, high pass filters, band stop filters, diplexers and triplexers. Our filters cover passbands from DC to 40 GHz, supporting many applications including WIMAX, WiFi, Zigbee, Bluetooth, GPS and SatCom, and many more. Mini-Circuits' RF filters are offered in coaxial connectorized, surface mount, MMIC die, and waveguide interfaces. In addition to our extensive catalog of parts available off the shelf, Mini-Circuits has decades of experience developing custom RF filters for customers with special requirements.
