DESCRIPTION
The SA9502 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 typically 12
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=11.1dB, NF=8.4dB, IIP3= +1.8dBm
–
CDMA:
Gain=11.3dB, NF=9.4dB, IIP3= +5.7dBm
–
FM:
Gain= 7.5dB, NF=10.5dB, IIP3= +6.2dBm
Separate, selectable IF outputs to suit FM and CDMA bandwiths
PCS mixer LO: direct or via internal frequency doubler
Switchable wideband LO output buffer
Low voltage operation down to 2.7V
Low current consumption in “idle”/receive modes:
–
PCS :
14.3mA @ 2.7V
–
CDMA:
17.6mA @ 2.7V
–
FM:
6.8mA @ 2.7V
Low standby current in sleep mode, typically 12
μ
A
