... ZNBG6000/1 contains 6. The negative rail generator is common to all devices. The drain voltage of the external FET Q This is determined by the on board V 2.2 volts whilst the ZNBG4001/6001 provides nominally 2 volts. The drain current taken by the FET is monitored by the low value resistor I driving the gate of the FET adjusts the gate voltage of Q the current called for by an external resistor R different drain currents into selected FETs ...

... The following diagrams show the ZNBG4000/1 and ZNBG6000/1 in typical LNB applications. Within each FET gain stage the numbering system indicates how the bias stages relate to the application circuits. This is important when RCAL values are used to set differing drain currents.
