SAN DIEGO, CA 92121-1714 http://www.cdmatech.com <[email protected]> T (858)658-5005 F (858)658-1556 T E C H N O L O G I E S C D M A Q U A L C O M M MSM6000 CHIPSET SOLUTION MSM6000 TM radioOne TECHNOLOGY radioOne is a revolutionary technology for CDMA transceivers that uses Zero Intermediate Frequency (ZIF), or direct conversion, architecture for the wireless handset market. This direct conversion eliminates the need for large IF Surface Acoustic Wave (SAW) filters and additional IF circuitry, which reduces the handset BOM, resulting in cost-effective multiband and multimode handsets that can be produced in smaller form factors. Using advanced techniques developed by QCT to enable high-dynamic-range receivers, radioOne solves the problem of stringent interference specifications with which CDMA phones must comply. radioOne technology also incorporates the frequency synthesis and passive elements used in converting baseband signals to and from RF. A single external local oscillator is used for the CDMA receiver, which will provide the capabilities needed to operate on systems around the world and will simplify the procurement of parts and greatly reduce the cost of designing CDMA handsets. new radioOne RF ASICs. Subsystems within the MSM6000 device include a CDMA processor, a DFM processor, QCT’s QDSP2000™ DSP for voice coding, PLL and an ARM7TDMI® microprocessor. Also integrated in the MSM6000 device are an audio voice codec and analog interfaces for the radioOne RF ASICs. Controllers for an R-UIM (CDMA SIM), GPIOs, and peripheral interfaces complete the system integration. compliant with IS-2000 Release 0, which addresses key attributes of network voice capacity improvements and significantly extended handset standby times.

Both LNAs utilize three gain settings that are programmable through the Serial Bus Interface (SBI) Operating modes—Sleep, Rx, and Rx/Tx, as well as LNA bias currents, are all automatically adjusted via software to minimize DC power consumption. Depending on handset status, the LNA bias current adjusts automatically to meet RF performance requirements with minimal power consumption. The device is fabricated using a SiGe BiCMOS process, which is suited for high performance RF circuits. The RFL6000 device is packaged in a very small 16-pin bump chip carrier (16-pin BCC++).

The device has 3 mixers which, when combined with the RFL6000 device, provide full RF-to-baseband down conversion for the cellular, PCS, and GPS band. The LO generation block produces all LO signals so that only one external single band VCO is required for all CDMA frequency bands of operation. Included on chip is the GPS LNA as well as the entire GPS VCO including resonant components. The Rx PLL, which resides on the transmit companion IC, the RFT6100 device, is switched between the GPS VCO and the external Rx VCO. Extension of standby time is achieved by selective circuit power down, gain control, and bias current. These features along with all of radioOne chipset functionalities are controlled by QUALCOMM’s MSM (Mobile Station Modem). The device is designed to operate with 2.7-to-3.1volt power supplies and is compatible with single-cell Li-Ion batteries. Compatibility to the lower voltage (1.8 to 3.1 volts) is assured when the VDDM is connected to the MSM pad voltage. The RFR6000 device is fabricated using a SiGe BiCMOS process, which provide high frequency, high-precision analog circuits as well as lowpower CMOS functions.

This transmit chip consists of I/Q modulators, one for Cellular and the other for the PCS band. The baseband I/Q input from the MSM directly modulates the Cellular or PCS carrier derived from the respective LO generation circuit. Both the Cellular and PCS output drive their own variable gain amplifier (VGA) with a gain control range of 85 dB. A final Cellular driver amplifier provides a modulated RF output. To accommodate split band and filtering, the PCS VGA drives two output amplifiers that can be selected independently or simultaneously via an input selectable switch. All RF outputs have fully integrated 50-ohm matching networks. Integrated on the RFT6100 is the receiver PLL, the transmit PLL, and the entire transmit VCO including resonant components. The VCO drives the LO generation block which in turn generates the required Local Oscillator signal for all CDMA bands of operation.
