RF Bias Tees 1.5A High Current, Low Loss, High DC-RF Isolation, 10 MHz - 4 GHz

INSTOCK Wireless bias tees are offered with N-type, SMA, TNC, & BNC coaxial connector options. All models INSTOCK and ready to ship. Mix-and-match connector customization also available. Contact us today for custom Bias T requirements.

A bias tee is a 3-port device commonly used to introduce DC current into a bidirectional RF transmission line without detrimental effect to the RF path. A common application of the bias tee is to power a remotely located active antenna or low-noise amplifier. INSTOCK Wireless 1.5A high-current bias tees provide best-in-class electrical performance demonstrated by 0.15 dB insertion loss and 65 dB isolation (avg) from 10 MHz to 4 GHz.
