Bias Tee

Posted by: Web Admin July 13, 2020 No Comments

The bias tee is a diplexer. The low-frequency port is used to set the bias; the high-frequency port passes the radio-frequency signals but blocks the biasing levels; the combined port connects to the device, which sees both the bias and RF. It is called a tee because the 3 ports are often arranged in the shape of a T.

A bias tee is used to insert DC power into an AC signal to power remote antenna amplifiers or other devices.

We offer Bias Tee up to 50GHz with different connector options.

Bias tees are used in a variety of applications, Power over Ethernet, active antennas, low-noise amplifiers, and down converters, lab testing.
