Frequency Range 10 MHz to 18 GHz

Bias Tees help add/remove DC current or voltage to/from RF circuits without impacting the RF signal. Typical applications include biasing active antennas, amplifiers and laser diodes, and for DC blocking or return in broadband microwave, RF and data communications. TTE’s BTS Series is a standard series designed to address a range of frequencies, from 10 MHz to 18 GHz. They are provided with SMA female connectors. Please contact TTE for additional options.
