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.

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 FETs for Power Management
• FET Drain Voltages and currents Held Stable Overtemperature and VCC Variations
• FETs Protected Against Overstress During Powerup and Powerdown.
• Internal negative Supply Generator Allowing Single Supply Operation (Available for External use)
• Low Quiescent Supply Current, 1.6mA Typical
• Low External Component Count
