摘要： A device and method are disclosed for synthesizing a waveform having pulse segments. An exemplary generator can include units having a time delay element and pulse generator generating the pulse segments. An input divider divides an input signal into signal instances that propagate through the units and an output combiner combines pulse segments to form the waveform. The pulse generators include a sharpening circuit for sharpening a rising edge and a falling edge of the pulse segments. The sharpening circuit includes a tunable delay element coupled to a non-linear transmission line (NLTL). Another NLTL can be coupled in parallel with the tunable delay element and the first NLTL. The NLTLs include input sections coupled to anodes or cathodes of Schottky diode elements, and the respective cathodes or anodes are coupled to a signal ground.

摘要： A modulator is provided that comprises a nonlinear transmission line (NLTL) that is bias modulated by a baseband signal. A given logic state of the baseband signal determines a delay amount of a first carrier signal through the NLTL. The modulator further comprises an impulse forming network (IFN) that includes a first NLTL that receives the first carrier signal delayed by the determined delay amount and a second NLTL that receives a second carrier signal having a fixed delay amount. The first NLTL and second NLTL within the IFN have opposite diode polarity configurations. The modulator further comprises a power combiner that converts a delta delay of the first carrier signal relative to the second carrier signal to a sharp impulse that represents the given logic state of the baseband signal.

摘要： A pulse generating circuit and related method, for producing extremely narrow pulses for use in monolithic microwave integrated circuits (MMICs) for radar, high-speed sampling, pulse radio and other applications. A sinusoidal input signal is supplied to two nonlinear shock wave generators, which are oppositely biased to produce periodic outputs that are mirror images of each other, one with a very steep rising edge and one with a very steep falling edge. The combined outputs would cancel each other completely but for the introduction of a slight time delay in one of them, which results in a narrow peak in the combined signals.

摘要： A ferroelectric loaded waveguide resonator capable of operation at microwave, millimeter-wave and higher frequencies and suitable for integration into a three-dimensional monolithic microwave integrated circuit (3D MMIC) is disclosed. The resonator includes a resonator cavity, which, in one form of the invention, is formed by two parallel metal layers and a metallized wall structure extending between the metal layers. The cavity is filled with dielectric material and includes a layer of ferroelectric material, which is used to control the resonant frequency by varying a voltage bias applied to the ferroelectric layer. The cavity includes a slot in one of the metal layers and a coupling strip formed adjacent to the slot to provide electromagnetic coupling to other components, such as a voltage controlled oscillator (VCO). The invention can also be applied to other multi-metal semiconductor or wafer level packaging technologies.

摘要： A comb frequency generator that is tunable to vary the width of the pulses in the output signal and achieve a maximum power output at different harmonic frequencies. A wavefront compression device receives a sinusoidal input signal and provides wavefront compression to create a compressed signal having a series of periodic fast edges. A delay device receives the fast-edge compressed signal and delays the fast-edge signal to create a delayed fast-edge signal. A combining device receives the original fast-edge compressed signal and the delayed fast-edge compressed signal to generate an output signal including a series of pulses having a width determined by the delay of the delayed signal. In one embodiment, the delay device is a shorted transmission line stub having a length selectively set by a series of MEM devices. In another embodiment, the delay device is an NLTL variable time delay device that delays the fast-edge signal.
