Abstract :
This paper describes a method of utilizing the voltage tuning characteristics of ferroelectric capacitors in a wide range, superheterodyne, dielectric-tuned, panoramic receiver. Continuous tuning over a 2:1 frequency band is obtained in frequency ranges up to 110 mc. Some of the problems encountered in this application are described, and a method of optimizing the parameters of specific materials is discussed. No detailed technical discussion is presented. The application of these capacitors to various types of circuitry is briefly indicated.
