摘要： A portable frequency synthesizer is provided with fine tuning over a broad bandwidth using a Fractional N type Delta Sum Phase Locked Loop circuit that enables elimination of boundary value spurs. In the system, frequencies where spurs occur are calculated to define a region of fractional N values that cannot be used with a first time base. To avoid the boundary spurs, a second time base reference is selected that can generate boundary spurs that do not overlap with the first time base. Circuitry is provided to select the appropriate time base and the fractional N values to generate desired output frequencies throughout the synthesizer range while avoiding the boundary spurs.

摘要： A spectrum analyzer is provided with frequency-scalable circuit architectures that extend the bandwidth of the spectrum analyzer using an array of couplers. The array of couplers is distributed along the RF signal path at one end, and interfaced to one or more frequency-translation devices such as mixers or samplers at the other. In a first architecture, a single mixer is employed with an LO signal applied to one input and coupler outputs providing RF signals to another input, with switching controlled to select one coupler's RF output to provide to the mixer. In a second architecture, a separate mixer is used, one for each coupler RF signal, with switches selecting one of the mixer IF outputs to select a desired output frequency. Both the first and second embodiments eliminate switching and its associated loss and frequency limitations from the main RF signal path to enable wideband high-dynamic-range spectrum analysis.

The electro-thermal transducer includes an impedance matched, bifurcated load supported over the aperture by the insulating membrane, and a thermopile extending over the aperture and supported by the insulating membrane, the thermopile being adapted to generate a voltage in response to heat generated in the impedance matched, bifurcated load. A signal conductor is electrically connected with one end of the impedance matched, bifurcated load to guide electromagnetic signals to the load, and a conductive under-layer stratified from the signal conductor by an intermediary dielectric is connected with an opposite end of the impedance matched, bifurcated load to act as a ground plane.

摘要： A small light-weight battery operated calibrator device provides a precise sine wave output for use in calibration of test equipment, such as a RF Power Meter or a Spectrum Analyzer. The calibration device includes two power levels, one −40 dBm and one 0 dBm. The purpose of the two power levels is to obtain a slope and offset for correction of the RF power measuring device being calibrated. Operation indication LED lights are provided to indicate which of the two powers are in use, and if battery power is below acceptable levels. Miniature low power components including a crystal oscillator and a divide by 2 integrated circuit that generates a precise square wave and a low pass filter for converting the square wave into a precise sine wave allows the calibrator to be battery operated and stored as a calibration component.

摘要： A Pseudo Random Bit Sequence (PRBS) generator is provided with components to enable operation at very high microwave frequencies with inexpensive components. The PRBS generator initially replaces the D flip-flops of a conventional PRBS generator with delay lines connected in a similar manner. Further, an exclusive OR (EXOR) gate used in a conventional device is replaced in one embodiment by a mixer and amplifier. In another embodiment, the EXOR gate is replaced by a Gilbert Cell. In some embodiments, complementary outputs of an EXOR gate are connected to separate delay lines to reduce components needed for the PRBS generator.

摘要： Systems in accordance with embodiments of the present invention can include an adapter having a sliding portion (a slider) slidable to expose an interface, thereby allowing mating—for example, between a test port and a DUT—to be observed and adjusted as required. The slider is removable, allowing an adapter sex change. In one embodiment, an insertion tool is provided which can hold a dual male pin and allow installation and removal of the dual male pin while assisting mating alignment. After calibration, the slider can be locked in place and the adapter can function as a standard coaxial connector.

摘要： Embodiments of the present invention are directed towards systems, methods, and computer readable media for performing multiport vector network analysis. Embodiments of the present invention relate to a multiport network analysis that is derived from a family of two port calibration techniques including Thru/Reflect/Line(TRL), Thru/Reflect/Match(TRM), Line/Reflect/Line (LRL), Line/Reflect/Match (LRM) and several others. An improved calibration method enables the use of a simplified switch matrix to perform accurate vector network analysis in communications and networking systems. After determining some characteristics through conventional methods, a two tier load match correction is performed on the results. The improved correction mechanism enables the system to perform comparably to systems with more complicated switch matrices.
