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.
Applications
˙Satellite
receiver LNBs
˙Private
mobile radio (PMR)
˙Cellular
telephones
