SAN DIEGO -- November 12, 2003 -- Qualcomm Incorporated (Nasdaq: QCOM), pioneer and world leader of Code Division Multiple Access (CDMA) digital wireless technology, today announced the receive diversity radioOne™ Zero Intermediate Frequency (ZIF) RFR6500™ device. Receive Diversity uses additional antennas and associated receive chains to enable improved signal reception, enabling higher data throughput and significant increases in network capacity for CDMA2000 1X and 1xEV-DO networks, especially in dense urban environments.

The RFR6500 chip incorporates the RF receive components that previously required two receive chips. This consolidated, single-chip solution reduces bill-of-material (BOM) costs and enables smaller form factor designs. Designed for CDMA2000 1X and 1xEV-DO networks, the RFR6500 chip is backward compatible with existing CDMA2000 networks, resulting in a seamless migration path without added research and development costs. Samples of the RFR6500 device are expected to ship in the fourth quarter of 2004.

"Qualcomm has proven receive diversity to be a competitive differentiator for CDMA operators offering data services," said Dr. Sanjay K. Jha, president of Qualcomm CDMA Technologies. "Our successful efforts in integrating receive diversity represent another significant milestone towards increasing network capacity."

Wireless devices supported by Qualcomm's RFR6500 receive diversity solution will have lower power consumption, smaller form factors and fewer dropped calls, while providing operators with products that improve forward link performance (from base station to wireless device).

The RFR6500 features the following:

  • Integrated receive components for diversity formerly requiring two separate chips: CDMA2000 1X receivers for both cellular and PCS bands
  • Integrated low noise amplifiers (LNAs), direct down converters, phase locked loop (PLL) and voltage control oscillator (VCO)
  • Integrated GPS receiver allowing for simultaneous GPS operations with CDMA2000

The RFR6500 chip interfaces with Qualcomm's MSM6500™ Mobile Station Modem™ (MSM™), MSM6550 chipset and system software solutions, and with future diversity-enabled MSM chipsets.
