ZABG6002
LOW POWER 6 STAGE FET LNA AND MIXER BIAS CONTROLLER
Summary
The ZABG6002 is a programmable low power depletion mode FET bias and mixer controller intended primarily for
satellite Low Noise Blocks (LNBs). Designed to provide system flexibility the ZABG6002 can be programmed to bias
six low noise amplifier (LNA) stages or four LNA and two active mixer stages, allowing the ZABG6002 to be used in
several system designs.
Combining advanced IC process and packaging techniques, the ZABG6002 operates with minimal current over a
wide supply voltage. The small package and reduced component count minimizes the PCB area whilst enhancing
overall LNB reliability.
Features
Pin Assignments
• 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 power-
up and power-down.
• Internal negative supply generator allowing single
supply operation (available for external use)
• Low quiescent supply current, 1.6mA typical
• Low external component count
Applications
• Twin LNB’s
• Quad LNB’s
• US LNB’s
• Microwave links
• PMR and Cellular telephone systems
