INTEGRATED CIRCUITS SA9502 Dual-band, CDMA/AMPS downconverter IC Product specification Supersedes data of 1998 Dec 10 IC17 Data Handbook 1999 Mar 19 Philips Semiconductors Product specification 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. – CDMA: Gain=11.3dB, NF=9.4dB, IIP3= +5.7dBm – FM: Gain= 7.5dB, NF=10.5dB, IIP3= +6.2dBm 14.3mA @ 2.7V – CDMA: 17.6mA @ 2.7V – FM: 6.8mA @ 2.7V APPLICATIONS • PCS and cellular downconverter mixers typical performance: Gain=11.1dB, NF=8.4dB, IIP3= +1.8dBm – PCS : • Low standby current in sleep mode, typically 12 µA • TSSOP20 package FEATURES – PCS: SA9502 • 800MHz analog FM and CDMA digital receivers • 1900MHz PCS band CDMA digital recievers • Supports dual-mode and triple-mode operation • Digital mobile communications equipment • Portable, low power radio equipment • Separate, selectable IF outputs to suit FM and CDMA bandwiths • PCS mixer LO: direct or via internal frequency doubler ORDERING INFORMATION PACKAGE EXTENDED TYPE NUMBER PINS PIN POSITION MATERIAL CODE SA9502DH 20 TSSOP Plastic thin shrink small outline package; body 6.5 x 4.4 x 1.1 mm SOT360-1 1999 Mar 19 2 853–2135 21064 Philips Semiconductors Product specification Dual-band, CDMA/AMPS downconverter IC SA9502 BLOCK DIAGRAM CDMA IF BPF Fo = 85.38MHz BW = 1.23MHz RX BPF Fo = 1960 MHz BW = 60 MHz PCS_in 2 2 PCS 2 CDMA_Out 2 FM_Out 2 CELL ×2 RX BPF Fo = 881.5MHz BW = 45 MHz 2 2 Cell_in 2 1 2 1 FM IF BPF Fo = 85.38MHz BW = 30kHz 1 PCS LO PCS CELL SA9502 1 BIAS CTRL MODE SELECT LOGIC CDMA/FM PCS/CELL 1 LO OUT LO BUFFER ENABLE CEL LO IN VCC PWR ON/OFF SR01718 Figure 1.

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. 11 LO OUT SR01760 Figure 2.

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. 4 Philips Semiconductors Product specification Dual-band, CDMA/AMPS downconverter IC SA9502 ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁ ÁÁÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁÁ ÁÁÁÁ ÁÁÁÁ ABSOLUTE MAXIMUM RATINGS PARAMETER Supply voltage (VCC) RATINGS UNITS –0.3 to +6.0 V –0.3 to VCC+0.3 V Maximum power input +20 dBm Power dissipation, Tamb=25°C 800 mW Maximum operating junction temperature 150 °C –65 to +150 °C Logic input voltage Storage temperature RECOMMENDED OPERATING CONDITIONS LIMITS PARAMETER TEST CONDITIONS Supply voltage (VCC) Logic input voltage range UNITS MIN.
