RDA microelectronics Inc announced yesterday that the successful development of a Radio-Frequency (RF) chip in the domestically developed TD-SCDMA (time division-synchronous code division multiple access) technology, is now being manufactured in the country's handsets.
TD-SCDMA technology is a national standard for the third-generation (3G) telecommunications network, with two core technologies of RF and Baseband Chips. Currently, Baseband Chips have been developed domestically, but it's a first for the RF chips.
Semiconductor Manufacturing International Corporation has tested the newly developed RF chips, which adopt the globally advanced CMOS (Complementary Metal-Oxide Semiconductor) technology.
