Overview
FET BIAS CONTROLLER ISSUE 2 - JUNE 1998 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 resistors the devices provide drain voltage and current control for a number of 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.
The ZNBG4000/1 and ZNBG6000/1 contain four and six bias stages respectively.
In setting drain ...
