Abstract: A bipolar pulse generator is implemented in a simple structure while providing a high efficiency design having a relatively low total size, while still allowing access by fibers used to control a photoconductive switch that activates the generator. The bipolar pulse generator includes a stacked Blumlein generator structure with an additional transmission line connected to a load at its near end and short-circuited at its distal end. An extra transmission line is positioned between the Blumlein generator's structure and the load provides specified limited gap between positive and negative sub-pulses. The bipolar pulse generator further includes a bended Blumlein generator structure, in which an existing intrinsic “stray” transmission line is used to provide the bipolar pulse. Still further, bipolar pulse generator includes stepped transmission lines, with additional switches positioned between steps, which are charged by different voltages.

Abstract: A bipolar pulse generator includes a pair of two-conductor transmission lines coupled together with a load positioned between the two transmission lines. Two segments of one transmission line are charged and switchably coupled to two segments of the other transmission line to produce a bipolar pulse on the matched load. The generator may include two transmission line structures coupled together with a load positioned between each transmission line structures. The first transmission line structure may include a stepped transmission line and an embedded transmission line segment. A switch is coupled between the embedded transmission line segment and another segment of the transmission line structure. During operation, the first transmission line structure is charged to a potential with the switch in the open position and, when the switch is closed, the charge on the first transmission line structure together with the second transmission line structure generates a bipolar pulse on the matched load.

Abstract: Conductor segments are positioned within a two conductor transmission line in order to generate microwave pulses. The conductor segments are switchably coupled to one or the other of the transmission lines in parallel. Microwave pulses may be induced in the transmission line by closing the switches in a controlled manner to discharge successive segments into the transmission lines. The induced waves travel uninterrupted along the transmission lines in a desired direction.

Abstract: A bipolar pulse generator includes two, two-conductor transmission lines coupled together with a load positioned between the two transmission lines. Each conductor of a transmission line we define as a segment. Two segments of one transmission line are charged and switchably coupled to two segments of the other transmission line to produce a bipolar pulse on the matched load. This bipolar pulse generator may be implemented in a flat or a folded design. The generator may include two transmission line structures coupled together with a load positioned between each transmission line structures. The first transmission line structure may include a stepped transmission line and an embedded transmission line segment. A switch may be coupled between the embedded transmission line segment and another segment of the transmission line structure.

Abstract: Conductor segments are positioned within a transmission line structure in order to generate microwave pulses. The conductor segments are switchably coupled to one or the other of the transmission lines or to each other, in parallel with the transmission line structure. Microwave pulses will be induced in the transmission line by closing the switches in a controlled manner to discharge successive segments or successive groups of segments into the transmission lines. The induced waves travel uninterrupted along the transmission lines in a desired direction.

Abstract: A broadband transmission line impedance transformer performs impedance transformation with improved frequency response and efficiency across a wide operational bandwidth. In particular, the bandwidth of a transmission line 2:1 impedance transformer may be significantly increased by adding an additional compensating capacitor as an internal component between interconnected transmission lines. This capacitor effectively improves low frequency response for a given length of transmission lines and decreases mismatch in an entire frequency range. The overall bandwidth ratio increases at least twice and mismatch decreases.

Abstract: A system for direct optical control of electronic power semiconductors includes an optical triggering circuit at a first location, wherein said optical triggering circuit generates an optical trigger signal, a power circuit located at a second location remote from the first location, wherein said power circuit includes a photoconductor that is responsive to the optical trigger signal generated by the optical triggering circuit, and an optical cable coupling the optical triggering circuit to the power circuit. In operation, the power circuit is directly driven by the transmission of the optical trigger signal from the optical triggering circuit to the power circuit via the optical cable. Inductive elements or transformers may be applied to facilitate triggering performance.
