Title: The Innovations of Donald R Chambers

Introduction

Donald R Chambers is a notable inventor based in Menlo Park, California. He has made significant contributions to the field of microwave frequency circuits, holding two patents that showcase his innovative spirit and technical expertise.

Latest Patents

Chambers' latest patents include the "Semi-lumped Element Coupler" and the "Proximity Coupler." The Semi-lumped Element Coupler is a coupling circuit designed for microwave frequencies, featuring two conductors shaped like a W. These conductors are strategically deposited on a substrate, allowing the bases of the W's to oppose one another, forming two semi-lumped capacitances of different susceptance, separated by phasing line lengths. The Proximity Coupler, on the other hand, is designed for high-frequency circuits. It consists of conductors deposited on a substrate in the shape of a hollow dumbbell intersected by an X. This design allows for coupling primarily across sawtoothed shaped gaps in the dumbbell's center section, with additional coupling across gaps formed by spaced parallel connectors. The parallel conductors are equipped with phase delaying loops at opposite ends, enabling modifications to the coupling characteristics through dimensional changes of the loops.
