high current

Frequency Range 20 MHz to 6 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 BTHC Series is designed specifically for applications requiring high current capabilities up to 7 A DC. It is appropriate for frequencies from 20 MHz to 6 GHz. Parts are provided with SMA female connectors. Please contact TTE for additional options.
