Conexant Delivers RF Chipsets for 2G and 3G CDMA Applications

The CX74001 offers the highest level of integration in a tri-mode, dualband receiver (Rx) RFIC. The device is designed to meet the needs of both 2G and 3G cdma systems. Specifically targeting the cdmaOne, cdma2000, and AMPS markets in the U.S. and Korean cellular, Japan cellular, Korean PCS and U.S. PCS bands. The CX74001 is also designed to be suitable for wideband CDMA (WCDMA) applications in the IMT-2000 band. Programmable linearity is included in the RF front end to optimize power consumption at various input levels. A three-step cellular LNA, bypass PCS LNA, and a seperate enable for the internal VCO increases system performance and standby times.
