6 STAGE FET LNA BIAS CONTROLLER
Summary
The ZABG6003 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 a resistor, the ZABG6003 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 ZABG6003 only requires one resistor which controls the drain current of the first stage FETS (D1 and D4). The drain
current is set internally to 10mA for the remaining 4 FETs for the second and third stages. This allows the operating current of input FETs to be
adjusted to minimize noise, whilst the following FET stages are fixed to minimize the number of external components used.
