UHF RF Preselector Study.
Abstract
A theoretical analysis of superheterodyne design principles is presented with emphasis on noise figure, selectivity trade-off, spurious response, and image phasing mixers. Magnetically tunable filters were examined on a theoretical and practical basis. Problems associated with uhf microminiaturization are discussed. Examination of varactor tuning techniques, and a consideration of large signal effects are presented. Distributed and active inductors and their relative advantages and disadvantages are presented. Distortion and low-noise performance of FET and switching mixers are presented with comparisons of dynamic range. (Author)
