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.
