Nujira Demonstrates Multi-Channel High Efficiency RF Power Amplifier Operation.Nujira's HAT[TM] Technology and Evaluation Platform Enables Simultaneous Support of Three WCDMA (Wideband CDMA) A 3G high-speed digital data service provided by cellular carriers that use the TDMA or GSM technology worldwide, including AT&T (formerly Cingular) and T-Mobile in the U.S. Carriers CAMBRIDGE, England -- Nujira, the company leading the development of advanced high efficiency power amplifier technology for the wireless industry, today announced the successful demonstration of ultra-high efficiency RF Power Amplifier An RF power amplifier is a type of electronic amplifier used to convert a low-power radio-frequency signal into a larger signal of significant power, typically for driving the antenna of a transmitter. (PA) operation with three simultaneous full-bandwidth WCDMA carriers. "This demonstration is an industry first and a major milestone in the development of next generation high efficiency PAs," stated Gerard Wimpenny, CTO (Chief Technical Officer) The executive responsible for the technical direction of an organization. See CIO and salary survey. of Nujira. "Our ability to support three WCDMA carriers while achieving power efficiencies approaching 50% is unmatched by any other technology vendor, and we are continuing to push the bandwidth and efficiency envelope. The progress Nujira has made with this technically challenging, but incredibly useful and necessary technology, further establishes Nujira as a technology and market leader." The demonstration was performed using the latest release of Nujira's HAT[TM] Evaluation Platform which is currently being used by major OEMs for evaluation of the HAT technology. The Platform consists of a baseband module which replicates the traditional DPD DPD Department of Planning and Development DPD Dihydropyrimidine Dehydrogenase DPD Dead Peer Detection (Cisco) DPD Division of Parasitic Diseases (US CDC) DPD Dominant Wave Period DPD Drug Product Database (Digital Pre-Distortion) and lineariser components of a typical PA, plus an RF module consisting of an example PA using a standard LDMOS LDMOS Laterally Diffused Metal Oxide Semiconductor LDMOS Lateral DMOS LDMOS Lightly-Doped Drain Metal-Oxide Semiconductor LDMOS Lateral Diffusion Mosfet device, and Nujira's HAT Modulator Modulator Any device or circuit by means of which a desired signal is impressed upon a higher-frequency periodic wave known as a carrier. The process is called modulation. The modulator may vary the amplitude, frequency, or phase of the carrier. . Using the HAT Evaluation Platform, Nujira has been able to demonstrate operation with 1, 2 or 3 WCDMA channels, including dynamic channel reconfiguration and switching between 1, 2 and 3 channels. Nujira's HAT Evaluation Platform is supplied with comprehensive PC-based waveform creation, waveform capture and control software which allows customers to evaluate the performance of a HAT-enabled PA under different operating conditions. Wimpenny added, "The high power consumption and the environmental impact of current 3G networks is a serious cause of concern for all operators, with many now setting hard performance targets for their networks. Nujira continues to make significant progress in enabling more efficient 3G/WiMAX basestations and DVB (Digital Video Broadcasting) An international digital television (DTV) standard that is the European and Far Eastern counterpart of the North American ATSC standard. systems, and we expect Nujira will play a key role in helping operators meet these targets." About Nujira Nujira is the leading supplier of high efficiency power amplifier technology and related intellectual property for the wireless communications industry. Nujira's patented high power High Accuracy Tracking (HAT[TM]) Modulators for WCDMA, 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. 2000, DVB and WiMAX power amplifiers enable infrastructure OEMs to design more power-efficient, smaller, and cheaper base stations to meet the increasingly demanding needs of operators worldwide.
