QUALCOMM CDMA Technologies Announces 3G CDMA2000 1X Baseband-to-RF Transmit Processor.Business Editors/High-Tech Writers SAN DIEGO--(BUSINESS WIRE)--Dec. 3, 2001 RFT See DCA. RFT - Request For Technology 5600 Device with Triple PLL PLL - phase-locked loop Performs Complete Transmit Functions for Third-Generation Handsets QUALCOMM Incorporated (Nasdaq: QCOM QCOM Qualcomm, Inc. (stock symbol) ), pioneer and world leader of Code Division Multiple Access (CDMA (Code Division Multiple Access) A method for transmitting simultaneous signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular phone technology from QUALCOMM that operates in the 800 MHz band and 1.9 GHz PCS band. ) digital wireless technology, today announced the RFT5600(TM) baseband-to-radio frequency (RF) transmit processor. The RFT5600 device performs all transmit (Tx) signal processing functions required in wireless CDMA handsets between the analog baseband output from the Mobile Station Modem (MSM MSM - Micronetics Standard MUMPS (TM)) chip and power amplifier (PA) for IS-95A/B A/B Airborne A/B Afterburner (jet engines) A/B Air Blast A/B Answerback A/B Auto-brake A/B Air Bus A/B Afterburning and 3G CDMA2000 1X applications. The RFT5600 device, together with the PA, enables a complete two-chip Tx radio implementation using minimum circuitry for IS-95A/B and CDMA2000 1X single-mode, dual-mode, dual-band or tri-mode handsets. Leveraging previous RFT3100(TM) circuit designs and incorporating a triple phase locked loop (PLL) comprising an ultrahigh frequency (UHF (Ultra High Frequency) The range of electromagnetic frequencies from 300 MHz to 3 GHz. In the U.S., analog television has used UHF channels 52 to 69 in the 700 MHz band. ) PLL and receive (Rx) and Tx intermediate frequency (IF) PLLs, the RFT5600 device offers an advanced, tightly integrated IS-95A/B and CDMA2000 1X Tx solution that simplifies RF printed circuit board (PCB PCB: see polychlorinated biphenyl. PCB in full polychlorinated biphenyl Any of a class of highly stable organic compounds prepared by the reaction of chlorine with biphenyl, a two-ring compound. ) design, shortens development cycle time, and reduces handset material costs. "As part of our complete IS-95A/B and 3G CDMA2000 1X solution, the RFT5600 device will save handset manufacturers time, money and board space, and represents a highly integrated transmit processor solution," said Don Schrock, president of QUALCOMM CDMA Technologies. "Consumers will benefit from a more cost-effective Tx implementation that offers the benefits of advanced IS-95A/B and 3G CDMA2000 1X technologies." The RFT5600 device includes a quadrature baseband-to-IF upconverter, a programmable PLL for generating the Tx IF frequency, Tx IF voltage controlled oscillator oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air (VCO (1) (Voltage Controlled Oscillator) An oscillator that can be tuned over a wide range of frequencies by applying a voltage (tuning voltage) to it. Used in many applications such as radio tuners, VCOs are less costly than crystal oscillators, but not as stable. ), single sideband upconversion from IF to RF, one cellular and two Personal Communications Service Designed to meet the requirements for global CDMA markets, the RFT5600 device will operate over the following Tx frequency ranges: 824 megahertz (MHz) -- 925 MHz (cellular band) and 1750 MHz -- 1980 MHz (PCS band). The range of supply voltage is from 2.7 volts (V) to 3.3 V, which provides operating compatibility for platforms using a single-cell lithium-ion (Li-Ion) battery design. RFT5600 operating modes are controlled by the MSM chip and include band selection and frequency programming, gain control, selective power-down, and punctured CDMA transmission (gated Tx power) for optimal power savings and talk-time improvement. The RFT5600 device is fabricated on an advanced bipolar complementary metal oxide semiconductor See CMOS.
