Bias Tees

Mini-Circuits is your complete source for bias tees, handling up to 4 Amps DC and covering 100 kHz to 12 GHz!

  • Rugged coaxial models
  • Tiny surface mount packages as small as 0.15 x 0.15 in
  • Excellent isolation
  • 50 and 75 Ohm models

Mini-Circuits RF/microwave bias-tees and diplexers provide extremely wideband performance with high isolation. All of our bias tees boast low insertion loss and VSWR. Our patented TCBT-series LTCC ceramic designs are the smallest in the world, ideal for designs where low cost, space limitation, and temperature stability are critical with performance as wide as 10 MHz to 10 GHz. Our ultra-wideband coaxial ZX85 bias-tees use our patented unibody construction to provide small size and high repeatability with performance as wideband as 0.2 to 12,000 MHz. Whether your applications call for biasing amplifiers, laser diodes, or active antennas, DC blocking, DC return, satellite communications, test setups, or if you have custom requirements, let us fit your needs "to-a-TEE!"
