SA9502Dual-band, CDMA/AMPS downconverter IC
21999 Mar 19 853–2135 21064
DESCRIPTIONThe SA9502 integrates all the front end receive
mixers necessaryfor use in dual-band, triple-mode CDMA/AMPS
cellular phonehandsets. There are three individual mixer blocks,
each optimisedfor high linearity with low power consumption for
operation in one ofthe following modes: High-band 1900MHz PCS CDMA,
low-band800MHz cellular CDMA or analog FM AMPS/TACS
modes.Additionally, the entire circuit can be powered down and put
intosleep mode, reducing the supply current to typically 12 µA.
Thecircuit has been designed in our advanced QUBiC2 BiCMOSprocess
with 20GHz fT.
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 µA• TSSOP20

FUNCTIONAL DESCRIPTION
Mode Selection LogicThe SA9502 downconverter IC has several
modes of operation forwhich the selection logic is summarized in
Table 1 and defined indetail in Table 2. Different mode selections
require different portionsof the circuit to be active. It should be
noted that only the statesspecified in Table 2 are valid selections
for operation.
Local Oscillator SectionLocal oscillator drive for the mixers is
provided through single endedinputs on either pin 16 (CEL LO) or
pin 14 (PCS LO). The LO signalhas to be AC-coupled into the circuit
and needs to be externallymatched. Inside the circuit, the cellular
band LO signal is amplifiedand buffered to drive: Either the
cellular CDMA mixer or FM mixeror the frequency doubler for the PCS
mixer LO and additionally theLO output buffer. The mode selection
summary in Table 1 shows thelogic to apply to pins 6 and 17 to
choose one of four possiblemodes. The LO output buffer can be
programmed on or off via LOBuffer Enable (Pin 13). The LO output
buffer’s frequency is thesame as that used by the mixers.
Cellular and PCS MixersThe SA9502 has one single ended cellular
band RF input whichfeeds either the cellular CDMA mixer or the
cellular FM mixercircuits. Each mixer is optimized to meet cellular
band CDMA oranalog FM requirements. The cellular FM mixer has its
owndedicated differential output on pins 1 and 2 which should to
beexternally matched to the FM IF SAW filter. The cellular
CDMAmixer shares the same output pins with the CDMA PCS
mixer.Selection between these two mixers is via pin 6 (PCS/CEL) and
asthe two mixers are never on at the same time, it allows a
commonCDMA SAW filter to be used for both bands. The CDMA PCS
mixerhas a differential RF input which should be used with an
externalbalun matching circuit. To avoid upsetting the internal
biasing, theRF inputs at both cellular and PCS band mixers should
beAC-coupled in. The CDMA and FM IF mixer outputs are of the
opencollector type. So, they should be biased to the supply voltage
VCCwith external tuning inductors which can also serve in the
matchingof the IF SAW filter.

DefinitionsShort-form specification — The data in a short-form
specification is extracted from a full data sheet with the same
type number and title. Fordetailed information see the relevant
data sheet or data handbook.
Limiting values definition — Limiting values given are in
accordance with the Absolute Maximum Rating System (IEC 134).
Stress above oneor more of the limiting values may cause permanent
damage to the device. These are stress ratings only and operation
of the device at these orat any other conditions above those given
in the Characteristics sections of the specification is not
implied. Exposure to limiting values for extendedperiods may affect
device reliability.
