서울--(뉴스와이어)--Sunnada Communication, China’s leading wireless coverage solutions provider, announced today the company’s debut of China’s first high-efficiency Doherty Transmitter. The milestone was achieved by combining Sunnada’s high-efficiency technique, Doherty with Freescale’s performance-leading RF power laterally diffused MOS (LDMOS) transistors designed for broadcast applications.

The Sunnada DTV transmitter offers significant power savings and highest output power in its class for UHF applications. Not only does it mean critical cost-savings for broadcasters, it fully aligns with China’s go-green goals with the lowest emission of carbon dioxide and lowest power consumption.

“We are proud to achieve the world’s first commercially available advanced high-efficiency Doherty technologies, incubated at our own research and development labs. By having our own platforms, we will be able to shorten cycle time and compete effectively in the market place with other global OEMs,” commented Mr. Huang Hai-feng, Executive Vice President of Sunnada Communication. “This significant leap is made possible by our semiconductor device provider, Freescale Semiconductor, who is one of the world leaders in RF LDMOS technologies.”

Featuring Freescale’s MRF6VP3450H device, the transmitter offers 50 percent higher efficiency than competing UHF TV broadcast solutions while enabling system-level power reductions. Freescale’s MRF6VP3450H delivers more than 450 W peak power at P1dB with high efficiency throughout the UHF broadcast frequency band. Transmitters represent a significant operating cost for TV broadcasters, and a leading contributor to this operating cost is the power consumed by RF power amplifiers.

“Freescale is pleased to play a role in Sunnada’s significant accomplishment. Going green is clearly on most if not all countries’ and corporations’ agenda. There is a marked increase in the number of low-power community broadcasters and full-power broadcasters which actively search for ways to lower energy consumption,” said Gavin Woods, vice president and general manager of Freescale’s RF Division. “Transmitters designed with our MRF6VP3450H device can not only deliver dramatic annual energy savings, but also can significantly reduce transmitter cost by helping to minimize the number of required RF power transistors.”
