Bias Tee / DC Injector For Coaxial RF

Bias Tee / DC Injector - SMA, Type-N & BNC

Narda-MITEQ now offers DC Injectors also known as Bias Tees or Bias T.  A Bias Tee is a coaxial RF device used to apply DC Power to the center conductor of a coax line while DC is blocked from one RF Port. 

We offer Bias Tee / DC Injector models designed for SMA, Type-N and BNC connectors in Stainless Steel / Brass with nickel plating.

Please call us to discuss your needs for RF Bias Tee / DC Injector components with one of our RF design engineers.
