Overview
FET BIAS CONTROLLER DRAFT ISSUE A - DECEMBER 2000 DEVICE DESCRIPTION The ZNBR 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 and a VCC of 3-6V for improved efficiency.
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 ZNBR4000/1 and ZNBR6000/1 contain four...
