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 f_T.

Features

• PCS and cellular downconverter mixers typical performance:
  – PCS: Gain=11.1dB, NF=8.4dB, IIP3= +1.8dBm
  – CDMA: Gain=11.3dB, NF=9.4dB, IIP3= +5.7dBm
  – FM: Gain= 7.5dB, NF=10.5dB, IIP3= +6.2dBm
• Separate, selectable IF outputs to suit FM and CDMA bandwiths
• PCS mixer LO: direct or via internal frequency doubler
• Switchable wideband LO output buffer
• Low voltage operation down to 2.7V
• Low current consumption in “idle”/receive modes:
  – PCS : 14.3mA @ 2.7V
  – CDMA: 17.6mA @ 2.7V
  – FM: 6.8mA @ 2.7V
• Low standby current in sleep mode, typically 12 µA
• TSSOP20 package

Applications

• 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
