Abstract:
Interconnect feed devices (10) are provided for electrically connecting first and second electrical components (17, 21). The interconnect feed devices (10) can include a dielectric shell (23) with an electrically-conductive coating (40), and leads (22) positioned within individual conduits (30) of the shell. Each lead (22) and its associated conduit (30) can act as a coaxial cable for transmitting radio frequency (RF) energy between the first and second electrical components (17, 21). The shell (23) can be manufactured using a process, such as stereolithography, that allows the shell to be formed with relatively complicated geometries, which in turn can facilitate relatively complicated cable routing.

Abstract:
Method and apparatus for producing a variable delay for an RF signal. The method can include the step of propagating the RF signal along an RF transmission line, coupling a fluidic dielectric to the RF transmission line, and dynamically changing a composition of the fluidic dielectric to selectively vary its permittivity in response to a time delay control signal. The method can also include the step of dynamically changing a composition of the fluidic dielectric to vary its permeability. The permittivity and the permeability can be varied concurrently in response to the time delay control signal. In a preferred embodiment the method can include selectively varying the permeability concurrently with the permittivity to maintain a characteristic impedance of the transmission line approximately constant.
