Provides bias for GaAs and HEMT FETs Drives up to three FETs Dynamic FET protection Drai.
is the enhanced 22kHz tone detection and logic output feature which is used to enable high and low band frequency switch.
The ZNBG series of devices are designed to meet the bias requirements of GaAs and HEMT FETs commonly used in satellite receiver LNBs, PMR cellular telephones etc. with a minimum of external components. With the addition of two capacitors and a resist.
