ZABG6002 Description
The ZABG series of devices are designed to meet the bias requirements of GaAs and HEMT FETs monly used in satellite receiver LNBs with a minimum of external ponents whilst operating from a minimal voltage supply and using minimal current. The ZABG6002 has six FET bias stages that can be user programmed to provide either a two plus four arrangement of amplifier FET stages or a two plus two arrangement of amplifier...
ZABG6002 Key Features
- Six stage FET bias controller, two configurable as mixer stages
- Operating range of 3.0V to 8.0V
- Amplifier FET drain voltages set at 2.0V, mixer drain voltage set at 0.25V
- Amplifier FET drain current selectable from 0 to 15mA, mixer current from 0 to 7.5mA
- Switchable FET’s for power management
- FET drain voltages and currents held stable over temperature and VCC variations
- FETs protected against overstress during powerup and power-down
- Internal negative supply generator allowing single supply operation (available for external use)
- Low quiescent supply current, 1.6mA typical
- Low external ponent count
