INTEGRATED CIRCUITS SA9500 Dual-band, CDMA/AMPS downconverter IC Product specification Supersedes data of 1998 Jul 07 IC17 Data Handbook 1998 Aug 11 Philips Semiconductors Philips Semiconductors Product specification Dual-band, CDMA/AMPS downconverter IC 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 20µA. The circuit has been designed in our advanced QUBiC2 BiCMOS process with 20GHz fT. Programmable wideband LO output buffer Low voltage operation down to 2.7V Low current consumption in “idle”/receive modes: – PCS : – CDMA: – FM: 20.0mA @ 2.7V 20.2mA @ 2.7V 7.7mA @ 2.7V Low standby current in sleep mode <20µA TSSOP20 package APPLICATIONS FEATURES – PCS: – CDMA: – FM: PCS and cellular downconverter mixers typical performance: Gain=11.3dB, NF=8.3dB, IIP3= +1.4dBm Gain=10.7dB, NF=9.6dB, IIP3= +6.3dBm 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 ORDERING INFORMATION EXTENDED TYPE NUMBER SA9500DH 800...
