Part Number : ZNBG3210
Function : FET bias controller
Manufacturers : Zetex => Diodes
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 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.
