RF Couplers

Over 475 low-cost models to choose from with power handling from 0.5 to 250W, covering 5 kHz to 18 GHz!

  • Directional/bi-directional/DC pass-through models
  • Surface mount and coaxial
  • Wideband core-and-wire and LTCC models as small as 0.12 x 0.06"
  • 50 and 75Ω

Mini-Circuits directional and bi-directional RF couplers are designed for a wide range of commercial, industrial, and military applications. Our low-cost surface mount models include LTCC designs as small as 1206 with low insertion loss and high directivity, while high-power surface mount designs offer power handling up to 100W.  Our extensive selection of coaxial connectorized couplers includes models with power handling up to 250W and a variety of packages featuring SMA, BNC, Type N, and TNC connectors. All units are manufactured to ensure statistical control of performance parameters such as insertion loss, coupling, and input/output return loss, ensuring outstanding unit-to-unit repeatability. With wideband coverage from 5 kHz up to 18 GHz, these RF couplers provide coupling ratios from 6 to 40 dB, DC passing and DC blocking to meet a broad range of system requirements.
