Abstract: A portable imaging apparatus and system. A sample processing device has a reaction chamber configured to receive a sample and react the sample with a fluorescent compound that emits a specified wavelength of light when excited by light within an excitation band. An illumination source can be positioned to illuminate the reaction chamber when the sample processing device is positioned for imaging. A light guide can be positioned to face the reaction chamber and transfer the emitted light to an imaging detector. The light guide has a filter that blocks the wavelength of light from the illumination source and passes the fluorescent emitted light. The light guide unit defines an angular light acceptance range and is configured to constrain angular spreading of light.

Abstract: A triple-band bandpass filter with at least one cavity resonator. Each cavity resonator has the same three orthogonal resonances modes corresponding to three unique resonance frequencies. The three unique resonance frequencies define the passbands of the filter. The filter has an input probe coupled to an input cavity resonator. The filter has an output probe coupled to an output cavity resonator. The input and output probes are shaped to concurrently couple signal waveforms in each of the resonance modes. Coupling probes that can be used as input or output probes are also provided. An inter-cavity coupling operable to concurrently transmit signal waveforms in each of the resonance modes is also provided. The inter-cavity coupling can be used to transmit signals between adjacent cavity resonators in the filter.

Abstract: A half wave dielectric resonator assembly including a resonator cavity having a top surface and a bottom surface, an elongated cylindrical dielectric resonator positioned within said resonator cavity and first and second insulative supports to couple and insulate the ends of the cylindrical dielectric resonator from the resonator cavity. The dielectric resonator has a substantially small diameter to length ratio. The resonator assembly provides improved spurious performance and quality factor (Q) at a lower mass. A resonator filter is constructed using a plurality of these resonator assemblies, where adjacent pairs of said resonator cavities are separated from each other by a common cavity wall. By forming a first iris opening formed within a first common cavity wall and forming a second iris opening formed within a second common cavity wall having a position that is vertically offset from the position of the first iris, it is possible to reduce stray coupling.

Abstract: A waveguide assembly for operation over a range of temperatures includes a waveguide body and a plurality of restraining strips coupled to the waveguide body. The waveguide body includes a pre-curved narrow sidewall of material having a first coefficient of thermal expansion (CTE). The restraining strips are coupled to the waveguide body at first and second lateral points on either side of the pre-curved narrow sidewall laterally and are spaced apart along the length of the waveguide body, and are made from a material having a second CTE much less than the first CTE. Thus, when the temperature of the waveguide assembly changes, the restraining strips maintain a substantially constant lateral distance between said first and second lateral points over the range of temperatures such that as the length of the waveguide varies with temperature, the curvature of the pre-curved narrow sidewall also changes, causing the effective large dimension of the waveguide assembly to vary such that the combination of said changes results in a constant phase length for said waveguide body.

Abstract: A microwave filter has a plurality of resonators and at least one transmission line mounted on a substrate having a ground plane. The filter can have input and output couplings that are transmission lines formed on the substrate or it can have input and output probes. The resonators have one or more gaps extending entirely therethrough, the gaps splitting the resonators into two or more slices. The transmission lines extend into the gap to couple energy into or out of a resonator or between two adjacent resonators. The transmission lines can have tapered ends or can be located off center so that they are closer to one side of a gap than to another side.

Abstract: A low loss surface acoustic wave (SAW) filter and method of operation thereof uses non-sequential coupling and, more particularly, cross-coupling to achieve good rejection characteristics with low loss. Strips of metallization are used with a circuit formed of a thin film of metallization. The strips are oriented parallel to an edge of each resonator being cross-coupled. In a six resonator filter, the second and fifth resonators are cross-coupled.

Abstract: A microwave filter has a plurality of resonant cavities with each cavity containing a dielectric resonator. There are self-equalizing probes or self-equalizing apertures located between some of the cavities. A circulator is connected to an output of the filter. The circulator has an input/output which is connected to an equalizer. The equalizer contains a dielectric resonator that is slightly different from the dielectric resonators of the filter to permit the equalizer to be tuned at a slightly different frequency from the filter. The equalizer and self-equalizing probes or apertures are capable of being operated to reduce a dispersive slope of the filter. The filter can operate in a single mode or a dual mode. The electrical performance of the filter is superior to prior art filters, particularly in the wideband versions because the dispersive slope is reduced.
