Abstract
A variable true time delay line () includes an RF transmission line () and at least one fluidic delay unit (). The fluidic delay unit includes a fluidic dielectric contained in a cavity () and coupled to the RF transmission line () along at least a portion of a length thereof. At least one pump is provided for adding and removing the fluid dielectric to the cavity () in response to a time delay control signal. A propagation delay of the RF transmission line is selectively varied by adding and removing the fluid dielectric from the cavity.
