Abstract

Our project objective was to evaluate a new circuit topology to explore if it could be integrated into an existing superheterodyne receiver chain, making a smaller and simpler RF front-end. A traditional superheterodyne receiver was built and measured so we could easily compare and contrast characteristics between the two models. Using the same parameters, we evaluated the new wide-band track-and-hold amplifier and compared the two models. Our testing and research has shown that while the device does work, the following significant problems must be overcome for the track-and-hold amplifier to be implemented in the superheterodyne chain: rotating IF frequency, poor linearity, instability at integer multiples of the clock, and precise phase locking.
