SA9502
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 A. The circuit has been designed in our advanced QUBiC2 BiCMOS process with 20GHz fT.

FUNCTIONAL DESCRIPTION Mode Selection Logic
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.
