Microwave and Millimeter Wave Phase Shifter.
Abstract
The present invention is directed generally to a variable phase shifter for millimeter wave signals, and more particularly to a variable phase shifter based on the slow-wave effect. There is increased interest in millimeter wave signal propagation both for military and commercial applications. The millimeter wave region is of interest because there are certain windows in the atmosphere in the millimeter wave region that will propagate millimeter waves for great distances. Additionally, millimeter waves will propagate through chaff and rain. In view of this interest, it is highly desirable to have millimeter wave circuit components which are compatible with solid state processing mothods, require reduced real estate area, have a decreased cost per device, and an increased yield. The phase shifter is an integral component of millimeter wave receivers, as well as other key RF components such as antennas, amplifiers, transmit-receiver switches, local oscillators and filters.
