Popis
In this proposal, AlphaSense, Inc. (AI) and the Carnegie Mellon University (CMU) detail the development of RF front end based on MEMS components for miniaturized digital EVA radio. Key innovations of our approach include: a) the use of a novel parallel receiver front end architecture based on MEMS components, b) a novel design of a high Q mixer-filter for RF mixing and IF filtering, and c) the implementation of band pass filter and voltage controlled oscillator (VCO) using CMOS fabrication technique. Consequently, the proposed EVA radio has the following merits: a)Small size, light- weight and low power consumption, b)High sensitivity and frequency selectivity, c)Good device reliability, and d)Easy device fabrication and low manufacturing cost.
