Qualcomm RFR6500 RFR6500

Qualcomm’s RFR6500 is a receiver that can simultaneously support GPS and CDMA2000 voice calls. The RFR6500 device also supports simultaneous hybrid dual-receive operation, which allows for 1X paging signal monitoring during a 1xEV-DO connection, while monitoring other frequency bands for hand-off. The RFR6500 solution incorporates dual-band, dual-diversity receive components (receivers for both cellular and PCS bands) into a single chip - reducing bill-of-materials (BOM) costs and enabling smaller form factor designs. This device also integrates low noise amplifiers, direct down converters, phase locked loop and voltage control oscillator.
