Bias T

NEW!

Need a way to couple 12VDC to a coaxial cable for a remote amp?

This device accompanies the Hi-Z Preamp and the High Gain amplifier allowing +12VDC to flow up the coax, while blocking DC to the receiver.

Constructed with all SMD components, the circuit is small and simple. Just connect the coax cables and power.

This little package has SMA for RF in/out and accepts +12V DC. The DC is fed to the amplifier stage(s) and blocked from the Rx.

Available Purchase Options:

SMD components assembled on the PCB. Fully function, but no connectors or case. $10
SMD assembled PCB + SMA's (not installed) + enclosure (not drilled) $15
Fully assembled PCB + SMA's installed in enclosure $20
