摘要： A logarithmic detector amplifying (LDA) system is provided for use as a high sensitivity receive booster or replacement for a low noise amplifier in a receive chain of a communication device. The LDA system may include an amplifying circuit configured to receive an input signal having a first frequency and generate an oscillation based on the input signal, a sampling circuit coupled to the amplifying circuit and configured to terminate the oscillation based on a predetermined threshold to generate a series of modulated pulses, and one or more resonant circuits including at least one variable capacitor, coupled with the amplifying circuit and configured to establish a frequency of operation and generate an output signal having a second frequency being substantially the same as the first frequency, with the operating frequency being adjustable in response to baseband information received from the system via the one or more variable capacitors.

摘要： Source radio frequency energy (RF) is coupled wirelessly, with no direct physical contact, between two compound loop (CPL) antennas across a variety of barriers such as plastic, human tissues, glass, and air. The compound coupling interface is highly efficient in transferring the RF energy from a source including one CPL antenna to a destination including a second CPL antenna. A re-radiating structure including a further CPL antenna or a different type of antenna may be connected on the destination side to completely physically isolate the source side from the destination side. When the destination coupling antenna is removed, the source coupling antenna may operate as an efficient radiator at the desired operating frequencies. Likewise, the destination coupling antenna may operate as an efficient radiator in the absence of the source coupling antenna.

摘要： Embodiments are directed to an antenna builder and a method of building and maintaining an antenna design repository. A first embodiment consists of an antenna builder that enables the creation of an antenna representation that can subsequently be output into a plurality of formats to be used by other tools, such as electromagnetic simulation software. An alternative embodiment is directed to a method of building and maintaining a repository of antenna designs. The repository of antenna designs can be queried, enabling a plurality of users to search for specific antenna designs. Alternative embodiments can enable a user to search the repository antenna designs by visually browsing over the antenna designs in the repository. The repository of antenna designs is created by saving solutions generated by an optimizer during an optimization run to the repository. Solutions from the repository can also be used to seed and bootstrap other optimization runs.

摘要： Embodiments are directed to a RF combiner/splitter having a first port separated from a second port and a third port by a generally tapering microstrip section. The second and third ports are separated by a generally rectangular bridge bar having a width selected to match the impedance of devices to be connected to the second and third ports and a length selected to provide a separation between the second and third ports of approximately quarter wavelength at a center point of an operational frequency of the devices. In a first embodiment, a horizontal RF choke joint is positioned between the first port and the tapering section. In a second embodiment, one choke joint is positioned between the second port and the bridge bar and a second choke joint is positioned between the third port and the bridge bar.

摘要： A regenerative selective logarithmic detector amplifier (LDA) can have integrated FM demodulation capabilities. It can receive a wired or wireless FM modulated signal and amplify or demodulate it with high sensitivity, high skirt ratio and minimized noise when compared to the prior art. When used in conjunction with other circuits such as a PLL or mixer, it can improve interference rejection and frequency selectivity and be locked on a precise channel in frequency and phase. The LDA produces intermittent oscillations that are self-quenched when reaching a given threshold. It also embeds the circuitry to perform direct FM discrimination. FM demodulation process is completed by a simple analog or digital frequency to voltage converter. This plus the fact that the instantaneous regeneration gain is low-medium permit to detect signals of small amplitudes buried in the noise.
