ZNBG4003 Datasheet (Diodes Incorporated) - 4 STAGE FET LNA BIAS CONTROLLER

ZNBG4003, 4 STAGE FET LNA BIAS CONTROLLER

The ZNBG series of devices are designed to meet the bias requirements of GaAs and HEMT FETs commonly used in satellite receiver LNBs with a minimum of external components.

The ZNBG4003 provides four FET bias stages, arranged in two pairs of two.

Resistors connected to pins Rcal1 and Rcal2 set the FE

ZNBG4003 Features

* Four stage FET bias controller Operating range of 5.0V to 8.0V FET drain voltages set at 2.0V FET drain current selectable from 0 to 15mA Allows first and second stage FETs to be run at different (optimum) drain currents FET drain voltages and currents stable over temperature FETs protecte
