ZNBG3210 datasheet

Description :

The ZNBG3210, 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 three 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.


 Provides bias for GaAs and HEMT FETs

• Drives up to three FETs

• Dynamic FET protection

• Drain current set by external resistor

• Regulated negative rail generator

requires only 2 external capacitors


• Choice in drain voltage
