The world's first WLAN IEEE802.11a/b/g + DVB-H radio frequency chip has reportedly been developed at the Suzhou Chinese Academy of Sciences Semiconductor Integration Research and Development Center, a spin-off of the CAS Institute of Semiconductors.
As a wireless local area network device, it is capable of operating between 2.4 and 5.825GHz multi-mode frequency bands. In addition, it supports DVB-H high definition digital mobile TV and the existing analog television. The multi-functional chip is power saving, with nearly the same power consumption as a single-functional device.
It has been developed independently by CAS researchers and has filed for invention patents. It is the first of its kind in the world, marking China's technology for high-end radio frequency chips is at the cutting edge of research in the field.
With the support of the CAS Knowledge Innovation Program, researchers from the CAS Institute of Semiconductors started their work on the WLAN chips in May 2004. One year later, they made breakthrough progress in the research and development of direct digital frequency synthesizer chips with synthesized clock frequency up to 2GHz, doubling the speed of similar products in the world at that time.
