NEC Corp. has announced the development of what the company claims to be one of the world's most efficient transmitter amplifiers for mobile base stations, a 2.1 GHz model that produces 45 W of output power per 100 W of power consumption. The company has produced these latest amplifiers by adopting high performance and highly reliable RF transistor technologies, in addition to independently optimizing Doherty RF circuitry with harmonic tuning.

Transmitter amplifiers are essential to the performance of mobile base stations, and as a result of the introduction of this new technology telecom operators may now anticipate meaningful cost reductions. Mobile base stations fitted with the latest transmitter amplifiers are expected to be significantly smaller and to consume less power than existing equipment, which decreases the space required for storing units, time needed to assemble the stations and simplifies maintenance.

NEC plans to begin shipment of the new transmitter amplifier, installed within LTE equipment, by the end of 2009. Looking forward, the company also aims to provide the transmitter amplifier for W-CDMA, LTE and WiMAX base station vendors throughout expanding global markets.
