Dual-band, CDMA/AMPS downconverter IC
• Switchable wideband LO output buffer
• Low voltage operation down to 2.7V
• Low current consumption in “idle”/receive modes:
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 fT.

The SA9502 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
Local oscillator drive for the mixers is provided through single ended
inputs on either pin 16 (CEL LO) or pin 14 (PCS LO). The LO signal
has to be AC-coupled into the circuit and needs to be externally
matched. Inside the circuit, the cellular band 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 the
LO output buffer. 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 be programmed on or off via LO
Buffer Enable (Pin 13). The LO output buffer’s frequency is the
same as that used by the mixers.

Cellular and PCS Mixers
The SA9502 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 to 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 in. The CDMA and FM IF mixer outputs are of the open
collector type. So, they should be biased to the supply voltage VCC
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.
Application information — Applications that are described herein for any of these products are for illustrative purposes only. Philips
Semiconductors make no representation or warranty that such applications will be suitable for the specified use without further testing or
modification.
Disclaimers
Life support — These products are not designed for use in life support appliances, devices or systems where malfunction of these products can
reasonably be expected to result in personal injury. Philips Semiconductors customers using or selling these products for use in such applications
do so at their own risk and agree to fully indemnify Philips Semiconductors for any damages resulting from such application.
Right to make changes — Philips Semiconductors reserves the right to make changes, without notice, in the products, including circuits, standard
cells, and/or software, described or contained herein in order to improve design and/or performance. Philips Semiconductors assumes no
responsibility or liability for the use of any of these products, conveys no license or title under any patent, copyright, or mask work right to these
