ZNBG2001 Datasheet (Zetex Semiconductors)

ZNBG2001, FET 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, 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
