Preliminary Product Information
FET BIAS CONTROLLER
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 respectively for the minimum in
devices size. Device operating temperature is -40
to 70°C to suit a wide range of environmental
conditions.
Aimtron reserves the right without notice to change this circuitry and specifications.
