    摘要： An electrical short-circuit for alternating-current (ac) microwave signals is physically positionable in direct response to an electrical bias control without an intermediary electromechanical converter. The electrically positionable short circuit includes at least first and second doped regions in a semiconductor, separated by a region in which the short circuit is formed between the doped regions by the bias. A first embodiment comprises discrete diodes connected between conductors at different locations, the discrete diodes having different forward junction voltages, so that varying the common bias voltage varies the number of conducting diodes and thus positions the short circuit in a stepwise manner. A FET embodiment includes various discrete MOSFETs having different conduction threshold voltages, and having their sources and drains connected at various points to the conductors to be short-circuited, so that variations of a common gate bias voltage selectively render one or more of the FETs conductive, thereby stepwise positioning the short-circuit. Distributed PIN and MOSFET structures provide continuous short circuit positioning as a monotonic function of bias. Two distinct modes of operation, pinchoff/resistive and a resistive/below-threshold are possible for the distributed FET embodiment. The electrically positionable short-circuit can be coupled to the conductors of a transmission line for effecting tuning, or can be coupled to a transmission line in such a way as to vary the signal path length and thereby provide phase shift.

    摘要： A threaded invar tuning screw extending through the threaded aperture of an invar bushing in the broad wall of a waveguide filter presents a capacitance inside the waveguide. This capacitance is varied by changing the depth of the screw in the waveguide in order to tune the filter. A brass locknut on the screw has a truncated, conically shaped bottom that mates with a similarly shaped countersunk hole on the bushing, the conical bottom, countersunk hole, and screw being coaxial. The mating surfaces on the nut and the countersunk hole reduce lateral movement of the screw during tuning and fixing of the position of the latter by tightening the locknut against the bushing.

    摘要： A variable waveguide impedance for the measurement of an active microwave element, for example in order to obtain a value of the figure of merit of the element, comprises a non-reflecting terminator consisting of two pyramidal parts mounted on a yoke which in turn is mounted on a first hollow shaft, and a shortcircuit device consisting of two metallic cylinders mounted on a second shaft. The second shaft is displaceable and lockable in the first shaft and the whole impedance device is arranged in a waveguide section in relation to which the impedance can be displaced by means of the first shaft. The active microwave element is connected to the waveguide section in order to establish a microwave field in the same.
