Controlling a time delay line by adding and removing a fluidic dielectric |
摘要 |
A variable true time delay line (100) includes an RF transmission line (110) and at least one fluidic delay unit (108). The fluidic delay unit includes a fluidic dielectric contained in a cavity (109) and coupled to the RF transmission line (110) 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 (109) 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.
