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.
