An application of advanced SiGe to millimeter-wave phased arrays

This talk will discuss a millimeter-wave defense application of SiGe-based phased arrays. The unique advantage of this technology is its ability to deliver large wafers with high yield and low-cost, coupled with acceptable RF performance such as NF and output power for 94 GHz applications. Also, the entire control circuitry can be integrated on the same chip using the SiGe BiCMOS process. System-level considerations will be described as the basis for understanding the suitability of the technology.
