DEVICE DESCRIPTION

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

With the addition of two capacitors and a resistor the devices provide drain voltage and current control for 3 external grounded source FETs, generating the regulated negative rail required for FET gate biasing whilst operating from a single supply. This negative bias, at -3 volts, can also be used to supply other external circuits.

FEATURES

? Provides bias for GaAs and HEMT FETs

? Regulated negative rail generator requires only 2 external capacitors

? Choice in drain voltage

? Wide supply voltage range

? QSOP surface mount package

APPLICATIONS

? Satellite receiver LNBs

? Private mobile radio (PMR)

? Cellular telephones

? Single in single out C Band LNB
