Silicon Germanium Carbon Module
Motorola has demonstrated integrated HBTs in their RF BiCMOS flow, with performance of 45 GHz and 90 GHz for f t and f max respectively, at half the current of traditional SiGe transistors. The addition of carbon provides excellent manufacturing latitude and a low noise figure. Motorola is able to achieve these performance characteristics with the addition of only one masking step into a proven mainstream process. The result is a cost-effective technology that lends itself to system-on-chip solutions, providing substantial cost efficiency for wireless applications such as radio architectures with optimized system partitioning.
