SA9500
Dual-band, CDMA/AMPS downconverter IC

1998 Aug 11
853–2109 19859
DESCRIPTION
The SA9500 integrates all the front end receive mixers necessary
for use in dual-band, triple-mode CDMA/AMPS cellular phone
handsets. There are three individual mixer blocks, each optimised
for high linearity with low power consumption for operation in one of
the following modes: High-band 1900MHz PCS CDMA, low-band
800MHz cellular CDMA or analog FM AMPS/TACS modes.
Additionally, the entire circuit can be powered down and put into
sleep mode, reducing the supply current to less than 20
μ
A. The
circuit has been designed in our advanced QUBiC2 BiCMOS
process with 20GHz f
T
.
FEATURES
PCS and cellular downconverter mixers typical performance:
–
PCS:
Gain=11.3dB, NF=8.3dB, IIP3= +1.4dBm
–
CDMA:
Gain=10.7dB, NF=9.6dB, IIP3= +6.3dBm
–
FM:
Gain= 7.2dB, NF=10.2dB, IIP3= +5.9dBm
Separate, selectable IF outputs to suit FM and CDMA bandwiths
Integrated frequency doubler for PCS mixer LO
Programmable wideband LO output buffer
Low voltage operation down to 2.7V
Low current consumption in “idle”/receive modes:
–
PCS :
20.0mA @ 2.7V
–
CDMA:
20.2mA @ 2.7V
–
FM:
7.7mA @ 2.7V
Low standby current in sleep mode <20
