Bias Tees provide a link in utilising a single coaxial cable to carry both RF signals and DC power, and with the recently announced ABT series from AtlanTecRF, this capability can now be provided for systems operating at frequencies up to 50GHz.
With RF connector choices of 2.92mm, SMA and Type N the actual frequency bands offered range from 10MHz - 2.5GHz through to 50KHz – 50GHz with DC voltage capability to 100V and current capacity to 2.5 A. A typical configuration would be a combination of male and female RF connectors for direct insertion into a RF line-up while the DC element is interfaced with a choice of solder post or a coaxial connector type, such as BNC. RF performance of a 50GHz unit includes 1.80:1 VSWR and 0.5 dB insertion loss.
AtlanTecRF offers a complementary range of DC blocks from stock, with standard units also available from stock.
AtlanTecRF Product Manager, Joanna Bolton commented, “These new Bias Tees enable DC power to be added to or subtracted from an RF signal line very efficiently, for the powering of amplifiers and other active circuitry in telecommunications and data transmission systems”.
