The objective of this research is to understand the design and performance of state-of-the-art silicon-germanium (SiGe) BiCMOS high-frequency circuits for phased- array radar and wireless communication systems operating in extreme environment conditions. This work investigates the performance of RF circuits over a wide- temperature and exposure to a radiation intensive environment. The design and characterization of a fully integrated transmit/receive (T/R) module and integra- tion onto a multi-element antenna array is presented. In addition, individual circuit blocks are characterized in these extreme environments.
