RF Bias Tees 10-4000 MHz, 1.5A, 100 VDC
Low loss, High RF-DC isolation

A Bias Tee is a 3-port device commonly used to transparently inject DC current into, or extract DC current from, a bidirectional RF transmission line, leaving the RF signal undisturbed. A blocking capacitor restricts DC current to the RF+DC out port only. A common bias tee application is powering a remotely located active antenna or low-noise amplifier through an RF coax line. Similarly, bias tees are used to tap DC off an RF coax line with existing DC feed.
INSTOCK Wireless bias tees operate from 10-4000 MHz handling high 1.5 A current at 50 VDC while providing best-in-class electrical performance demonstrated by low 0.15 dB insertion loss, high 60 dB RF-to-DC isolation, and exceptional 1.10:1 VSWR. Bias tees are offered with N-type, SMA, TNC, & BNC coaxial connector options with DC feed-through pin.
All models are INSTOCK and ready to ship. Mix-and-match connector customization also available. Contact us today with your custom Bias Tee requirement.
