ZNBG4003JA16TC

A Product Line of Diodes Incorporated ZNBG4003 4 STAGE LNA BIAS CONTROLLER Description Pin Assignments The ZNBG4003 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 NEW PRODUCT and microwave links. The ZNBG4003 provides each FET with a negative gate voltage and positive drain voltage with user programmable drain current. Features Top view • Four stage FET bias controller • Operating range of 4.75V to 8.0V • FET drain voltages set at 2.0V • FET drain current selectable from 0 to 15mA • Allows first and second stage FETs to be run at different (optimum) drain currents • FET drain voltages and currents stable over temperature • FETs protected against overstress during power-up and power- Bottom view down. • Internal negative supply generator allowing single supply Applications operation (available for external use) • Low external component count • Two single type Twin LNB’s • Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) • Twin LNB’s Halogen and Antimony Free. “Green” Device (Note 3) • Quad LNB’s • Notes: • Microwave links • PMR and Cellular telephone systems 1.
