Description
The AT1504 is 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 resistors the devices provide drain
voltage and current control for a number of external ground...
