L8001中文资料FET BIAS CONTROLLER数据手册UTC规格书

描述 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.

特性 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
