Bias T (Bias Tee) DC Injector

WATERPROOF FOR OUTDOOR or INDOOR USE

Telcosat Inc. is proud to introduce the 700MHz to 2.5GHz Bias T 32V DC Injector.

Bias T Image

Telcosat Bias Tees (Bias T) are passive coaxial devices used to inject DC currents or voltages into RF circuits without affecting the RF signal through the main transmission path. Bias tees are useful when trying to provide an RF signal and DC power to a remote device without running two separate cables.

Our Waterproof N Bias T design is rated for a minimum frequency of 700 MHz and a maximum frequency of 2.5 GHz.. All RF connectors are 50 Ohm N Female. This radio frequency wideband Bias T is manufactured to be rated for a maximum DC voltage of 32 Volts and a maximum current between 1A to 4A depending on the model selected.

In-line current limitation protects against current overload due to short circuits.

The PCB board is housed in a rugged case that is machined from a solid block of aluminum.

The physical design of the Bias T is extremely rugged and durable and would easily meet “military grade” standards. Able to withstand wide extremes of temperature a Telcosat Bias Tee is ideal for designs where low cost, high quality, space limitation, and outdoor all weather environments are critical.

Like all Telcosat products, the N Bias T is designed and manufactured in Canada.

If you have any questions regarding applications, please contact us today and a member of our design team would be pleased to assist you.
