General Description
The AS3801 is a gain controlled amplifier designed
for the transmit 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.
Applications
ì
Digital cellular systems with transmission
methods: CDMA/FDM, TDMA/FDM, FM/FDM
and TDMA/TDD.
ì
Examples: IS-95 CDMA, IS-54 DAMPS, AMPS,
PWT.
ì
Cordless phones analog / digital.
ì
General purpose linear IF amp’s.
ì
WLL / WLAN.
