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 grounded source FETs. The AT1504 is available in SSOP16 pin packages respectivel y for the minimum in devices size. Device operating temperature is -40 to 70°C to suit a wide range of environmental conditions.
