UNISONIC TECHNOLOGIES CO., LTD L8001 Preliminary FET BIAS CONTROLLER  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.
