| 20090167453 | METHOD AND APPARATUS FOR DIGITAL SYNTHESIS OF MICROWAVES THROUGH BALANCED TRANSMISSION LINE STRUCTURES - 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. | 07-02-2009 |

| 20100001807 | Method and apparatus for digital synthesis of long multi-cycle microwave pulses - Conductive segments (transmission line conductors) are positioned within a transmission line structure in order to generate multi-cycle microwave pulses. The conductor segments are switchably coupled to one or the other conductor of the transmission lines, inside the transmission line structure. Microwave pulses may 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 pulses travel uninterrupted along the transmission lines in a desired direction to the load. Efficiency of systems and energy delivered to the load in multi-section transmission lines is increased and/or maximized by adjusting the ratio of characteristic impedances associated with the transmission line conductor segments according to an optimum ratio. | 01-07-2010 |

| 20140035695 | FREQUENCY AGILE HIGH POWER MICROWAVE GENERATOR - A Multi-Cycle Digital High Power Microwave (MCD-HPM) source includes a microwave transmission line (MTL) to which a plurality electrically charged thin film transmission lines (TFTL's) are connected by switches. The switches are activated in sequence to generate a square wave at a microwave output frequency. The activation signal is controlled by a free space time delay, which can vary the timing and/or routing of the activation signal by modifying at least one free space element, thereby adjusting the switch activation timing and varying the output frequency. In embodiments, the switches are photo-conducting switches, the activation signal is a laser beam, and the switch timing is varied by reorienting and/or repositioning mirrors and/or other elements in the free space time delay. The elements can be manually adjusted, or mounted on motorized stages and automatically controlled. Optical amplifiers can be included to compensate for losses in the time delay elements. | 02-06-2014 |

An array of nonlinear and dispersive transmission lines, are arranged to generate RF pulses from the video pulses. At least one sensor is arranged to detect the leading edge of the video pulses after they have passed along the transmission lines. A phase controller is arranged to set the velocity of the video pulses in each transmission line to put the detected leading edges, and hence the generated RF pulses, into a desired phase relationship. | 02-05-2015 |
