Mini-Circuits Transformers

Over 260 models with rugged construction and repeatable performance from 0.15 to 8000 MHz

  • Wideband tiny surface mount or coaxial
  • LTCC models as small as 2 x 1.2mm
  • Cost-effective, custom solutions available!

Mini-Circuits RF transformers and baluns are offered in surface mount and connector packages and a wide variety of configurations for 50 and 75Ω systems. We have over 250 surface mount models in stock including baluns with impedance ratios from 1:1 to 1:4. Our Top Hat™ feature on open core surface mount models improves speed and accuracy of pick-and-place throughput, and our LTCC models feature wrap-around terminations for visual solder inspection in packages as small as 0805 (2mm x 1.2mm). Rugged coaxial connector models are available in DC blocking and DC passing designs with rugged metal cases and a variety of connector types including SMA, BNC, N-type, and F-type. Affordable custom designs are just a phone call away with surprisingly quick turnaround times gained from over 40 years of manufacturing and design experience.
