www.DataSheet4U.com PRODUCT SUMMARY CX74061: Rx ASIC for CDMA, AMPS, PCS, and GPS Mobile Handset Applications APPLICATIONS • Tri-band, quad-mode handsets • PCS and GPS phones • CDMA and GPS phones After RF LNA signal amplification and filtering from the antenna, the received signal is mixed down from RF to the IF. There are separate mixers for AMPS, CDMA-cellular, CDMAPCS, and GPS modes. The CDMA and PCS mixers have balanced outputs for the IF SAW filters, while the AMPS differential output can be combined externally to mate to a single-ended SAW filter. The GPS mixers have a differential output for an external L-C bandpass filter.
