Bias Tees / DC Blocks

Jan. 3, 2019
Pasternack bias tees (aka bias Ts) 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 or bias Ts 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 / bias Ts from stock the same day you order them. Pasternack Enterprises offers the broadest and deepest inventory of RF and microwave components available.
