Part Number : ZNBG3210
Function : FET Bias Controller
Package : QSOP 20 Pin type
Maker : Zetex , Diodes
Pinouts :
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.
Features
• 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
