The goal of the Phase I program is to demonstrate the potential for our approach and mitigate program risks for future development efforts. To achieve this goal, we will evaluate system level trade-offs, then design and simulate the key components. The system trade study followed by requirement definition will evaluate radiometry architectures and various PolyStrata implementations. Once a temperature detection level is decided upon, PolyStrata options will be evaluated on size, weight and power. Critical components will be designed including full wave EM modeling. Following the design, a filter section of the multiplexer and the LNA module will be fabricated and tested. The filter will specifically be tested for design and process repeatability whereas the module will evaluate LNA integration and mechanical module design features.
