Dual-band, CDMA/AMPS downconverter IC
SA9502
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
µA.
The
circuit has been designed in our advanced QUBiC2 BiCMOS
process with 20GHz f
T
