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
ต
A. The
circuit has been designed in our advanced QUBiC2 BiCMOS
process with 20GHz f
T
.

FUNCTIONAL DESCRIPTION
Mode Selection Logic
The SA9500 downconverter IC has several modes of operation for
which the selection logic is summarized in Table 1 and defined in
detail in Table 2. Different mode selections require different portions
of the circuit to be active. It should be noted that only the states
specified in Table 2 are valid selections for operation.
Local Oscillator Section
Drive for the local oscillator is provided through a single ended input
via pin16. The LO signal has to be AC-coupled into the circuit and
needs to be externally matched. Inside the circuit, the LO signal is
amplified and buffered to drive: Either the cellular CDMA mixer or
FM mixer or the frequency doubler for the PCS mixer LO and
additionally one of the LO output buffers. The mode selection
summary in Table 1 shows the logic to apply to pins 6 and 17 to
choose one of four possible modes. The LO output buffer can supply
either the same frequency as that input on pin 16 or doubled
frequency LO in CDMA PCS modes. The LO output power range
can be programmed between high gain and low gain (idle mode)
settings with LO gain on pin 13.
Cellular and PCS Mixers
The SA9500 has one single ended cellular band RF input which
feeds either the cellular CDMA mixer or the cellular FM mixer
circuits. Each mixer is optimized to meet cellular band CDMA or
analog FM requirements. The cellular FM mixer has its own
dedicated differential output on pins 1 and 2 which should be
externally matched to the FM IF SAW filter. The cellular CDMA
mixer shares the same output pins with the CDMA PCS mixer.
Selection between these two mixers is via pin 6 (PCS/CEL) and as
the two mixers are never on at the same time, it allows a common
CDMA SAW filter to be used for both bands. The CDMA PCS mixer
has a differential RF input which should be used with an external
balun matching circuit. To avoid upsetting the internal biasing, the
RF inputs at both cellular and PCS band mixers should be
AC-coupled. The CDMA and FM IF mixer outputs are of the open
collector type. So, they should be biased to the supply voltage V
CC
with external tuning inductors which can also serve in the matching
of the IF SAW filter.

Definitions
Short-form specification -- The data in a short-form specification is extracted from a full data sheet with the same type number and title. For
detailed 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 one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or
at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended
periods may affect device reliability.
