Abstract
The electrical operating characteristics of a microwave circuit are modified by providing a dielectric layer on the circuit in a pattern which modifies the electrical characteristics of an overlay responsive portion of the circuit in a manner which results in the overall circuit having a desired electrical operating characteristic within a tolerance. Adjustment of the operating characteristics may be done in an iterative manner of measuring the characteristics, modifying the distribution of dielectric material and remeasuring the operating characteristics until satisfactory operating characteristics are obtained. Alternatively, the operating characteristics may be adjusted in an interactive manner in which the circuit is provided with power and appropriate signals and its operating characteristics are monitored during the process of selectively removing dielectric material with the removal process being controlled in accordance with the current electrical operating characteristics and being terminated when a desired set of operating characteristics is obtained.
