Abstract: This invention pertains to a method by which the frequency and the modulation characteristics of a wire or wirelessly transmitted signal can be identified in a matter of milliseconds with significantly higher speed and accuracy than with existing or prior art receivers and spectrum analyzers, without erroneous image signals. Such signals can be then demodulated and decisions made based upon the demodulated data. The system then can be reconfigured to act as a transmit-receive module, with the transmit frequency enabled to address many different applications. This has applications in, terrestrial and satellite communications, and defense.

Abstract: This invention describes a method by which Broadband Spectrum Analysis can be performed in the RF and Microwave frequency range with significantly higher speed, accuracy, and flexibility than existing RF and Microwave Spectrum Analyzers. This is done by eliminating the need for the filtering of the incoming signal, a process called preselection that needs to track in frequency with the scanning local oscillator in the instrument. By eliminating this requirement, this invention makes possible the identification and analysis of very broadband signals in a single sweep using an Adaptive Sweep Methodology and a Simultaneous Sweep capability that the present invention makes possible.

Abstract: This invention describes a method by which a low cost low phase noise Phase Locked Loop or Phase Locked Loop based Frequency Synthesizer can be realized. The new method, called a Translational Phase Lock Loop or TPLL, allows the conversion of a traditional voltage controlled oscillator or VCO signal so that the phase noise of the VCO signal is substantially identical to the noise that the loop is aimed to correct via comparison to a low noise reference oscillator. It overcomes additional problems associated with traditional and prior art phase lock loops in terms of unwanted spurious signals, complexity, and cost.

Abstract: Single and multiple ferrite crystal resonator, oscillator, and filter coupling structures are disclosed. In one embodiment, a single ferrite crystal resonator coupling structure is configured as a single pole YIG-tuned-oscillator (YTO) coupling structure. The YTO coupling structure includes a circuit substrate having an upper and a lower side. The circuit substrate includes an aperture extending through the circuit substrate between first and second openings on the upper and lower sides, respectively. The aperture is configured to permit rotation of a ferrite crystal disposable at least partially therein about a plurality of axes whereby a desirable axis of the ferrite crystal is alignable with a magnetic field within the aperture. At least one coupling line through which an electric current can be directed, which extends between a first end and a second end of the first opening of the aperture across at least a portion of the first opening of the aperture.
