Mini circuits Bias Tee | Mini circuits Coaxial Bias Tee
Mini circuits Bias Tee is pupular.Mini circuits have introduced Bias Tee recently. Mini circuits Bias Tee has features such as Low insertion loss, better VSWR and RoHS compliant.
Bias Tee is used for various applications such as biasing of amplifiers, laser diodes, antennas. It is used for DC return, DC blocking and as test and measurement accessory.
Figure-1 depicts internals of Bias Tee. As shown it will have 3 ports. RF signals incident on port 1 will be delivered to the port-2 and DC is blocked by capacitor. On port-3 DC is passed and RF signal is blocked using inductor component.
Bias Tee selection Guide
In order to select Bias Tee for the application following parameters are to be considered.
• Frequency Range of Operation• Max. DC voltage and current• Impedance• VSWR• Insertion Loss• RF Connector type(SMA M/F etc.)
