SA9500
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 20A. The circuit has been designed in our advanced QUBiC2 BiCMOS process with 20GHz fT.

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 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.
