Abstract: The present invention provides target devices such as filter units with at least one receiving channel with a stop surface that is electrically conductive and at least one cable with a connector assembly on a first end portion. The connector assembly includes a first member with an open channel. The first member is coupled to the end portion of the outer conductor with the free end of the inner conductor and the end portion of the dielectric extending through the open channel to reside forward of the first member. The first member resides in a respective one of the at least one receiving channel against the stop surface. The connector assembly also includes second member with an open channel. The second member is slidably coupled to the first end portion of the at least one cable and presses the first member against the stop surface.

Abstract: A differential transmission line cable includes a notch filter to manage common-mode energy. The cable includes a narrow portion with two adjacent electrical conductors each having a narrow cross-sectional area and spaced at a narrow spacing. The cable also includes a wide portion longitudinally adjacent to the narrow portion. The wide portion includes the two adjacent electrical conductors each having a wide cross-sectional area greater than the narrow cross-sectional area and spaced at a wide spacing greater than the narrow spacing. The wide and narrow cross-sectional areas and spacings are specified so that the differential-mode impedance of the differential transmission line cable is uniform throughout both the narrow and wide portions and so that differences in the common-mode impedances of the narrow and wide portions create a notch filter to manage common-mode energy in the differential transmission line cable.

Abstract: A zeroing structure applicable to an adjustable diplexer includes a substrate, holder, motor, lead screw, displacement plate, stop element and interference element. The holder is disposed on the substrate. The motor is disposed on the holder. The lead screw is rotatably disposed on the holder and connected to the motor, and thus rotation of the lead screw is driven by the motor. The displacement plate is movably disposed on the substrate and helically connected to the lead screw so as to undergo linear motion between a first position and a second position relative to the substrate when guided and driven by the motor. The stop element is disposed on the lead screw. The interference element is disposed on the displacement plate and at the position that allows the interference element to come into contact with the stop element when the displacement plate is at the first position. The zeroing structure enables the adjustable diplexer operable at an adjustable center frequency to perform mechanical zeroing and enables primary or auxiliary confirmation of zeroing detection. Furthermore, the zeroing structure is highly reliable and incurs low cost.
