ZABG4003 4 STAGE FET LNA BIAS CONTROLLER

The ZABG series of devices are designed to meet the bias requirements of GaAs and HEMT FETs commonly used in satellite receiver LNBs with a minimum of external components whilst operating from a minimal voltage supply and using minimal current. The ZABG4003 has four FET bias stages that can be progr.

NEW PRODUCT ZABG4003 4 STAGE FET LNA BIAS CONTROLLER Summary The ZABG4003 is an advanced GaAs and HEMT FETs bias controller designed to operate from minimal supply rails and intended primarily for satellite Low Noise Blocks (LNBs). With the addition of one capacitor and two resistors, the ZABG4003 provides drain voltage and current control for up to 4 external grounded source FETs. Generating the regulated negative rail required for FET gate biasing whilst operating from a single supply of 2.1V.
