Mini-Circuits RF Filters

Mini-Circuits Filters Mini-Circuits provides a broad range of filters designed to separate, suppress, or select electrical and magnetic signals based on frequency. These products are applicable across various industries, from power lines carrying high currents to radio receivers detecting microvolt-level signals in GHz ranges.

RF Filters

  • Bandpass Filters: Passbands from 0.063 to 86 GHz, offering good rejection and selectivity with over 390 models in stock.
  • Low-Pass Filters: 3 dB cutoff up to 18 GHz, stopbands up to 26 GHz, with up to 40 dB rejection.
  • High-Pass Filters: Passbands up to 40 GHz, 3 dB cutoff as low as 0.055 MHz, with up to 41 dB rejection.
  • Diplexers and Triplexers: Passbands up to 20 GHz, providing excellent crossover isolation in both 50 Ohm and 75 Ohm models.
  • MMIC Reflectionless Filters: Patented designs that eliminate in-band spurs and terminate stopband signals internally, ideal for non-linear circuits.
  • LTCC Ceramic RF Filters: Compact, durable filters as small as 0402, with excellent power handling.
  • Waveguide Filters: Low insertion loss and high rejection, with passbands up to 86 GHz.

Mini-Circuits ZVBP Cavity Filters Mini-Circuits ZVBP Cavity Filters are designed for frequencies from 908 MHz to 40 GHz, offering high Q resonant structures that ensure low insertion loss and excellent power handling. These filters are ideal for applications like aerospace, defense, Satcom, 5G, and test and measurement.

Mini-Circuits Bandpass Filters

  • Surface Mount Bandpass Filters: Passbands from 2 MHz to 20.5 GHz, available in designs like lumped L-C, MMIC, LTCC, and ceramic resonator.
  • Coaxial Bandpass Filters: Rugged construction with low insertion loss and high rejection.
  • Cavity Bandpass Filters: Bandwidths as narrow as 1%, with outstanding selectivity and rejection up to 70 dB.
  • LTCC Ceramic Bandpass Filters: Available in the industry’s widest selection, with case sizes as small as 0402.
  • Waveguide Bandpass Filters: Instrument-grade machining, low insertion loss, and high stopband rejection up to 40 dB.

Mini-Circuits offers an extensive selection of RF filters, including low-pass, high-pass, band-pass, band-stop filters, as well as diplexers and triplexers, with over 3,000 models available for same-day shipping. They also provide custom filter designs with quick turnarounds to meet specific requirements.

With patented MMIC reflectionless filters, sharp-rejection cavity filters, and LTCC filters as small as 0603, Mini-Circuits supports applications across a wide frequency range, from DC to 86 GHz. Their RF filters are widely used in WiMAX, WiFi, Zigbee, Bluetooth, GPS, SatCom, and more, available in various interfaces like coaxial connectorized, surface mount, MMIC die, and waveguide.
