Pasternack Bias Tees

Bias Tees


Pasternack Bias Tees (also known as Bias T’s) are passive coaxial components

primarily used in applications where you need to inject DC currents or voltages

into RF circuits. Bias tees are designed to inject DC current into an RF circuit without

affecting the RF signal through the main transmission path. Our lines of bias tees are

used for applications where DC power is needed to power amplifiers on antennas or

other RF circuits. The “tee” in the name is derived from the shape of the 3 ports which is typically

in the shape of a T.


50 Ohm bias tees from Pasternack are available with two different bias connector designs including solder pin and SMA female. Other connector configurations for our bias tees include 2.4mm, 2.92mm, 3.5mm, Type N and SMA. Pasternack’s bias tees have maximum voltage ratings between 24 and 100 volts. Maximum DC current for our bias tees ranges from 200 mA to 7,000 mA (milliamps). Many of our RF bias tees are RoHS and REACH compliant.


The ISO 9001:2008 registered Pasternack facility ships all bias tees from stock the same day you order them.
