The Keysight 11612A (formerly Agilent) is a broadband bias network designed for a wide variety of biasing applications in laboratory and production environments. Operating from 45 MHz to 26.5 GHz, this bias tee provides a means of supplying up to 40 V and 500 mA DC bias to the center conductor of a coaxial line while blocking DC to the RF port, featuring low insertion loss and excellent SWR performance.
