摘要： A high-speed cross-point switch is built on a preferably silicon substrate and uses bipolar transistor switching elements. Preferably, the bipolar transistors are SiGe bipolar junction transistors. Intersecting conductive input and output microstrips are preferably thinned at their intersections to reduce shunt capacitance between the coupled lines. It is also preferred that the input buffer be connected in cascode fashion with the switching transistors in order to create an amplification stage. The signal and its inverse are carried on balanced microstrip pairs in order to reduce electromagnetic field strength at the center of the balanced line pairs thereby improving isolation between two crossing balanced pairs.

摘要： A combined matching and harmonic rejection circuit with increased harmonic rejection provided by a split resonance for one or more of the capacitive or inductive elements of the circuit. At a fundamental frequency, the circuit comprises an inductive series arm with capacitive shunt arms. The capacitance of a shunt arm may be provided by two or more parallel paths, each having a capacitor and an inductor in series so that, in addition to providing the effective capacitance necessary for impedance matching at the fundamental frequency, two separate harmonics represented by the series resonances of the parallel paths are rejected. In this manner, an extra null in the circuit's stop-band may be achieved using the same number of shunt elements necessary to achieve impedance matching at the fundamental frequency.

摘要： The invention relates to a system for electromagnetic processing of an input wave involving the steps of receiving a modified signal derived from two or more signals that represent the input wave when combined; and regulating the modified signal using a digital signal containing at least one characteristic of the two or more signals. Embodiments of the invention may utilize in-phase and quadrature phase signals, where the magnitude portion of the signals may be used for regulating the modified signal. The modified signal may be created by modulating a characteristic of the I, Q signals, such as their sign, with an RF or other frequency carrier wave.

摘要： A method and apparatus for producing a modulation scheme usable in conjunction with information transmission and reception via waveforms, such as electromagnetic waves. The modulation scheme is usable for such purposes as resolving range ambiguities and overcoming fading and interference problems via use of offset signals that vary in frequency over time (e.g., chirp signals), which spread the signal over a larger bandwidth. The method includes coding a symbol signal onto a split data stream containing a reference signal (e.g., a chirp), to which a time delay has been applied, then recombining the split streams to produce a composite waveform. The method can also include demodulating a composite received waveform by applying a reference signal to the waveform and then band pass filtering the waveform into discrete symbol data. Apparatus and systems are also provided for performing the method.

摘要： A transceiver and transmitter are shown. A baseband processor receives a signal for transmission. It converts the signal into amplitude and phase polar components. Each component is then processed—the phase component through a wideband phase modulator and the amplitude component through a wideband amplitude modulator, and the components are then recombined for further processing or transmission.
