TOKYO, JAPAN: Mitsubishi Electric Corp. will launch five new models of gallium arsenic (GaAs) power amplifiers to be used in personal computer (PC) data communication terminals for WCDMA cellular networks. Sales will begin on March 1, 2011 through Mitsubishi Electric sales sites worldwide.
With faster data transfer speeds of cellular networks, development of PC data communication terminals, such as data cards or USB terminals, has become extremely active. However, market demand for smaller terminals, which required more power output due to greater data traffic, created the issue of needing to limit heat accumulation as much as possible.
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.
