New Devices Bring Exceptional Performance to Ultra Linear Power Amplifiers Designed for Applications Up to 2.2 GHz Continuing to deliver market-leading solutions for new and emerging 3G wireless systems, Motorola, Inc. (NYSE: MOT) today announced their next generation of RF LDMOS devices designed specifically for the 3G base station infrastructure market. A recognized leader of RF LDMOS technologies, Motorola's new fifth generation high voltage product family (HV5) continues to support the industry as service providers begin to deploy 3G W-CDMA and UMTS wireless systems. Each device in this family will be optimized for specific frequency bands -- simplifying and providing the highest performance available.
Motorola's HV5 family of devices has adopted the earlier generation (HV4) advantages of providing ESD protection and minimization of hot carrier injection effects, while improving upon gain, efficiency and power densities. HV5 also establishes new industry benchmarks for RF power reliability-drift- free device design featuring typical Idq drift of less than three percent over twenty years and a new standard for ruggedness (minimum BVdss of 70V).
Motorola's HV5 family of RF LDMOS devices bring unprecedented performance to ultra-linear power amplifiers designed for W- CDMA/UMTS applications at 1.9 to 2.1 GHz. The stringent requirements of 3G protocols make device optimization and characterization imperative -- the HV5 family was designed specifically to provide the highest average power, while meeting the W-CDMA/UMTS specifications.
The new HV5 family is designed to deliver an average of 20% improvement in backoff efficiency over HV4 technology, a 1db increase in gain, as well as higher power density without sacrificing outstanding performance and linearity. These new devices will be fully characterized and individually tuned to operate at frequencies from 1.9 to 2.1 GHz and are suitable for all linear transmitter formats.
The first HV5 products to be unveiled are the MRF5S21090 and the MRF5P21180. The MRF5S21090 is a 90-watt single-ended device operating at 2.1 GHz. The MRF5S21090 device provides 90-watt peak power and 20-watt average W-CDMA power with a minimum of two- carrier linearity of -35dBc. The MRF5P21180 is a push-pull transistor that provides 180-watt peak power and 38-watt average W-CDMA power with a minimum two-carrier linearity of -35dBc.
"With the introduction of the HV5 family, Motorola has established new industry benchmarks in efficiency, linearity and ruggedness. Motorola's LDMOS also simplifies error correction with pre- distortion techniques," stated Graham Haddock, vice president and general manager of Motorola's Wireless Infrastructure System Division. "These advantages enable our customers to develop cost- effective and simplified designs where performance and time-to- market are critical success factors."
