... The ZNBG devices provide all the bias requirements for external FETs, including the generation of the negative supply required for gate biasing, from the single supply voltage.The diagram above shows a single stage from the ZNBG series. The ZNBG3010/11 contains 3 such stages. The negative rail generator is common to both devices. ...

... Should the negative bias generator be shorted or overloaded so that the drain current of the external FETs can no longer be controlled, the drain supply to FETs is shut down to avoid damage to the FETs by excessive drain current. ZNBG3010 ZNBG3011 pin. SUB ...

... ZNBG3010 ZNBG3011 The following schematic shows the function of the V numberd Q1 and Q2 are powered at any one time, their selection is controlled by the input V This input is designed to be wired to the power input of the LNB via a high value (10k) resistor. With the input voltage of the LNB set at or below 14V, FET Q2 will be enabled. With the input voltage at or above 15 ...

... The following block diagram shows the main section of an LNB designed for use with the Astra series of satellites. The ZNBG3010/11 is the core bias and control element of this circuit. The ZNBG provides the negative rail, FET bias control and polarisation switch control, with the minimum of external components ...
