Computational Techniques for the Reduction of Nonlinear Effects Using Passive Compensating Networks.

摘要

The objective of this effort is to develop design procedures to minimize nonlinear effects in mildly nonlinear circuits--Specifically, design procedures that will reduce nonlinear distortions such as intermodulation, desensitization, gain compression, etc. in communication equipment. The approach used relies on reducing in-band nonlinear distortion products by modifying the first order transfer functions outside the band of interest. The technique makes use of the fact that certain high-order nonlinear effects in the passband are functions of first-order network parameters at frequencies outside the band. By appropriate modification of these first-order parameters in-band, nonlinear effects can be reduced.
