Description

The ZABG6004 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 ZABG6004 provides drain voltage and current control for up to 6 external grounded source FETs. Generating the regulated negative rail required for FET gate biasing whilst operating from a single supply of 2.1V to 5V. The -2V negative bias can also be used to supply other external circuits. Setting drain currents on the ZABG6004 uses two resistors and drain current control is split between the six FETs in a group of two and a group of four. This allows the operating current of input FETs to be adjusted to minimize noise, whilst the following FET stages can be adjusted for maximum gain.
