DESCRIPTION
Downconverter typical performance
The SA9503 is an integrated CDMA/AMPS low noise amplifier
(LNA) plus a downconverter, for both the 900 MHz Cellular band and
the 1.9 GHz PCS band. The LNA incorporates 5 settings of digitally
selected stepped gain in the Cellular band and in the PCS band.
One of the modes (high linearity mode) in each of the Cellular and
PCS bands, includes a high IP3 setting in order to meet the 1-tone
CDMA desensitization test. The gain, noise figure and IP3 for the
remaining 4 low current modes in the Cellular band, are designed in
order to have sufficient separation between the antenna power
levels at which the LNA gains are changed, based on multi-tone
interference levels. A 3 dB overlap is allowed in the antenna power
levels for the adjacent modes. Table 1 indicates a typical scenario.

SA9503
FUNCTIONAL DESCRIPTION
Downconverter
The SA9503 has three mixers, one for Cellular FM, one for Cellular
CDMA, and one for PCS CDMA. Each one is individually optimized
for their specific requirements. The Cellular CDMA and FM mixers
have a common single-ended RF input.
Mode selection
The SA9503 has several modes of operation for which the selection
logic is defined in Tables 2 and 3. Different mode selections require
different portions of the circuit to be active. Modes from unlisted
combinations of logic pins are not permitted. The LNA and
downconverter together can be programmed to operate in the PCS
or cellular bands using the PCS/CEL logic input pin, and in CDMA or
FM modes using the CDMA/FM logic input pin.
The PCS mixer’s RF input port is differential, and requires an
external balun when used with a single-ended source. Both the PCS
and the Cellular mixer RF inputs should be AC coupled.
Local oscillator drive for the mixers is provided through pins
CEL LO_IN and/or PCS LO_IN. The local oscillator inputs are
single-ended, AC-coupled. The CEL LO_IN signal is internally
buffered to drive the following:
– (Tx) LO output buffer,
– cellular FM mixer,
– cellular CDMA mixer,
– PCS LO frequency doubler.
The LNA can be set to four different gain values and one special
high linearity setting. Thus, the LNA can be programmed into five
different modes with associated gain, noise figure, and input IP3,
using the S0, S1, and S2 control lines. The whole circuit (LNAs and
mixers) is powered down when control lines S0 = 1, S1 = 0, and
S2 = 0. It is also possible to independently switch off the LNAs and
keep the mixers on, as shown in Table 3.
LNA
In the PCS mode, mixer LO drive can be either direct (PCS LO_IN)
or through the frequency doubler after CEL LO_IN. The mixer local
oscillator signal is made available externally via the (Tx) LO output
buffer for potential use elsewhere in the radio. For example, this
signal typically can be used with the transmitter circuitry. The
(Tx) LO output buffer can be powered down independently, using
the (Tx) LO_ENABLE logic input. The (Tx) LO output buffer has
open collector differential outputs which are internally biased to
VCC2 supply rail.
External components can be used to match the LNA inputs, and if
required, the outputs, for the Cellular and PCS bands. The input and
output return loss of better than 10 dB can be achieved in all modes.
For Cellular band FM, only the CEL_1 mode is required for the LNA.
For CDMA, LNA modes CEL_1 and PCS_1 are used for normal
operation, as they have the highest gains and lowest noise figures.
For higher levels of multi-tone interference, other modes with lower
gains are to be used. The high linearity CEL_L and PCS_L modes
are used when there is a very strong adjacent channel interference,
while at the same time the mobile is transmitting close to its full
power. The high linearity is required in order to reduce the cross
modulation of the LNA from the mobile’s transmitter, in the presence
of strong adjacent channel interferer. The maximum transmitter
power leakage which can be tolerated at the LNA input is
approximately –30dBm to meet the single tone desensitization
requirements. The cross modulation power can be derived from:
The PCS and Cellular CDMA mixers have open collector differential
IF outputs. The two IF outputs can either supply two separate IF
filters, or they can be connected together externally for use with one
common receive IF filter. The differential IF outputs must be biased
at the supply voltage through external inductors that may also be
part of the matching circuit to the SAW filter. The cellular band FM
mixer also has a differential open collector IF output.
Cellular band: (2 × PTX + PJAMMER – 8) dBm
(2 × PTX + PJAMMER – 10.5) dBm
PCS band:
The LNA requires less than one hundred microseconds to settle
when it changes from one mode to another. This is expected to have
insignificant impact on the CDMA frame error rate.

MODE SELECT LOGIC AND DC CHARACTERISTICS
The SA9503 chip has several modes of operation for which the selection logic is defined in the following two tables. Different mode selections
require different portions of the circuit to be active. Modes from unlisted combinations of logic pins, are not valid. Total current consumption of
the device is the sum of the currents for the mixer portion (Table 2) and the LNA portion (Table 3).

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.
