Motorola Inc.'s Semiconductor Products Sector (SPS) has noted that they have made enhancements on its SiGe:C technology for wireless applications.

The improvements the company has put into its 0.185m and 0.355m SiGe:C heterojunction bipolar transistor (HBT) in a BiCMOS process is expected to provide longer battery life, meaning longer talk times for portable products including cellphones. According to Motorola, by optimizing the way the transistor is built, power consumption may be reduced by a factor of four, and a 60 percent improvement in peak frequency performance may be obtained, in comparison with the existing process.

Motorola has introduced several products using its first-generation 0.355m SiGe:C process, including the RF portion of its i.250 GSM/GPRS Innovative Convergence wireless platform. The 0.185m process was qualified in Q1of 2002, with products planned for early 2003.
