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.
   
FEATURES
• PCS and cellular downconverter mixers typical performance:
    – PCS: Gain=11.3dB, NF=8.3dB, IIP3= +1.4dBm
    – CDMA: Gain=10.7dB, NF=9.6dB, IIP3= +6.3dBm
    – FM: Gain= 7.2dB, NF=10.2dB, IIP3= +5.9dBm
• Separate, selectable IF outputs to suit FM and CDMA bandwiths
• Integrated frequency doubler for PCS mixer LO
• Programmable wideband LO output buffer
• Low voltage operation down to 2.7V
• Low current consumption in “idle”/receive modes:
    – PCS : 20.0mA @ 2.7V
    – CDMA: 20.2mA @ 2.7V
    – FM: 7.7mA @ 2.7V
• Low standby current in sleep mode <20µA
• TSSOP20 package
