NOT RECOMMENDED FOR NEW DESIGN USE ZABG4003 ZABG4002 LOW POWER 4 STAGE FET LNA BIAS CONTROLLER Summary The ZABG4002 is a four stage depletion mode FET bias controller intended primarily for satellite Low Noise Block’s (LNB’s), but its also suitable for other LNA applications such as those in found in PMR’s and microwave links. The ZABG4002 provides each FET with an independent protected negative gate voltage and positive drain voltage with user programmable drain current. Combining an advanced IC process and packaging techniques, the ZABG4002 helps minimise power consumption, component cost and PCB area whilst enhancing overall reliability.     D3 VCC D1 G1 D2 G3 ZABG 4002 G2 VCC D4 G4 GND RCAL1 R CAL2  (Top View) CSUB  Pin Assignments Four Stage FET Bias Controller Operating Range of 3.0V to 8.0V Low Quiescent Supply Current, 1.2mA Typical FET Drain Voltages Set at 2.0V FET Drain Current Selectable from 0 to 15mA Switchable FETs for Power Management Allows First and Second Stage FETs to Be Run at Different (Optimum) Drain Currents FET Drain Voltages and Currents Held Stable Over Temperature and VCC Variations FETs Protected against Overstress during Power-up and Powerdown Internal Negative Supply Generator Allowing Single Supply Operation (Available for External Use) Low External Component Count Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3) CNB1        CNB2 Features (Bottom View) CSUB Applications      Twin LNB’s Quad LNB’s US LNB’s Microwave Links PMR and Cellular Telephone Systems Notes: QFN1633 1.
