DESCRIPTION

The UTC L8002 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 L8002, provide six FETs bias control respectively.
By adjusting two internal 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
* Stable bias control for GaAs and HEMT FETs
* Drive up to six FETs
* 2.5V supply voltage
