Mitsubishi Electric will launch five new models of gallium arsenic (GaAs) power amplifiers to be used in personal computer (PC) data communication terminals for WCDMA 1 cellular networks. Mitsubishi Electric’s new GaAs power amplifiers achieve an industry-leading power added efficiency (PAE) of 45 percent, contributing to lower power consumption and heat emission.The amplifiers include a coupler monitoring the output power and an attenuator that switches the power gain.
The amplifiers are fully compliant with the European Restriction of the use of certain Hazardous Substances in electrical and electronic equipment (RoHS) directive. They are completely halogen-free, based on IEC (International Electrotechnical Commission) 61249-2-21. Sales will begin on March 1, 2011.
