ZNBG3210Q20 Datasheet Fet Bias Controller With Polarisation Switch And Tone Detection

Manufacturer: Zetex (now Diodes Incorporated)

Overview: FET BIAS CONTROLLER WITH POLARISATION SWITCH AND TONE DETECTION ISSUE 2 - FEBRUARY 2000.

General Description

The ZNBG series of devices are designed to meet the bias requirements of GaAs and HEMT FETs monly used in satellite receiver LNBs, PMR cellular telephones etc.

with a minimum of external ponents.

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.
