General Description
The AS3802 is a gain controlled amplifier designed
for the receive section of dual mode CDMA/FDM,
TDMA/FDM or FM/FDM cellular phones.
Key specifications like gain range noise figure, IP3,
temperature range and other specifications are
designed to be in line with the IS-95 Standard for
CDMA cellular communications.
The circuit is designed for narrow band IF
applications but can also be used in wideband
applications.
