    摘要: Described is an electron spin resonance (ESR) spectrometer comprising a miniaturized radio-frequency (RF) microwave cavity resonator. The miniaturized RF microwave cavity resonator receives a carrier signal from a circulator, modulates the signal path signal, and reflects the carrier signal back to the circulator to amplify the carrier signal prior to demodulation. A mixer receives and demodulates the carrier signal and outputs an audio signal to generate an ESR spectrum for analyzing a chemical composition of a fluid sample. The ESR spectrum represents a magnetic susceptibility of the fluid sample to a magnetic resonance cause variation in a resonant frequency of the miniaturized RF microwave cavity resonator. In a desired aspect, the carrier signal is split into two paths prior to demodulation. The two paths are demodulated by different mixers to produce two separate outputs, an absorption spectrum and a dispersion spectrum.

    摘要: Described is a miniature tunable filter, comprising at least two adjacent coaxial-type resonators coupled to one another. Each coaxial-type resonator comprises a metal-coated ceramic dielectric cavity having a tuning rod passage formed therethrough. A tuning rod is inserted through the tuning rod passage, such that the miniature tunable filter is tuned by moving the tuning rod into and out of the tuning rod passage of the ceramic dielectric cavity. A low impedance coaxial section surrounds at least a portion of the tuning rod to create an effective microwave short-circuit at a resonant frequency of the miniature tunable filter, which results in very wide tuning and low insertion loss. In a desired aspect, the tuning rod is a solid metal tuning rod. The combination of a solid metal tuning rod with a ceramic coaxial-type resonator results in high radio frequency power handling.

    摘要: A circuit component has an elastically deformable first structure, a second structure, and a support structure coupling the first and second structures, wherein the first structure can be variably deformed in response to a variable force, to provide either a variable capacitor or a variable tank circuit having a variable capacitor and an inductor. In one particular embodiment, a piezoelectric element is laminated to the surface of the first elastically deformable structure thereby providing the capability to deform the first structure. A method of making a circuit component includes forming an elastically deformable first structure, forming a second structure, and joining the first and second structures, to provide either a variable capacitor or a variable tank circuit having a variable capacitor and an inductor.
