The SKY77702 and the SKY77703 power amplifier modules from Skyworks Solutions have made it to the fourth generation (4G) of cellular technology, in Samsung's newest 4G mobile phone, the Craft. The Craft handset was designed as an entertainment device for providing fast connectivity to the Web and access to streaming video and music. The SKY77702 and the SKY77703 GaAs power amplifier modules (PAMs) were designed for Long Term Evolution (LTE) applications, with bandwidths of 1850 to 1910 MHz and 1710 to 185 MHz, respectively, and output power and power-added efficiency (PAE) of +28.5 at 40 percent and +28.4 dBm at 40 percent, respectively. Early this year, Skyworks enabled the world's first commercial LTE device, Samsung's high-speed 4G USB modem.

According to Gregory L. Waters, Executive Vice President and General Manager of front-end solutions at Skyworks, "Skyworks is delighted to once again be at the forefront of the technology powering next-generation devices that allow consumers to enjoy higher data rates and always-on connectivity. Our solutions benefit handset OEMs and smart phone providers, as well as infrastructure suppliers and operators worldwide by improving efficiency and performance, boosting network throughput, and simplifying roaming to provide the best consumer experience."
