RF delay lines with variable displacement fluidic dielectric |
摘要 |
A continuously variable true time delay line (100) and method for producing a time delay. The true delay line (100) includes an RF transmission line (110) and at least a first fluidic dielectric (130) contained in a cavity (109) coupled to the RF transmission line along at least a first length thereof. One or more variable displacement fluid processors (120) are provided for changing a distribution of the fluid dielectric (130) in the cavity (109) in response to a time delay control signal (137). The propagation delay of the line is selectively varied by changing the distribution of the fluid dielectric in the cavity.
