FET BIAS CONTROLLER
CMOS IC
DESCRIPTION
The UTC L8001 is specially designed integrated circuit for
satellite receiver front-end block. It provides stable drain and gate
bias conditions for GaAs or HEMT FETs.
The UTC L8001, provide six FETs bias control respectively.
By adjusting two external resistors, it can change the FET’s bias
current to optimize the satellite receiver front end block
performances.
It generates the required negative voltage to bias the gate of
GaAs FET, and internally provides protection circuit that can
protect the FET devices during supply voltage transient. So it is
very popular in satellite receiver front end block.
FEATURES
* Built in FET device protection circuit
* Adjustable FET device operating current
* Stable bias control for GaAs and HEMT FETs
* Drive up to six FETs
* Wide supply voltage range
