摘要： A multi-resonator crystal filter is provided having a reduced number of electrical connecting pins. The monolithic crystal filter includes at least four resonators, namely, an input resonator, an output resonator and electrically coupled center resonators. A single electrical pin connection is made to the electrically coupled together center resonators thus avoiding the need for an individual connecting pin for each resonator.

摘要： A dual-coupled monolithic crystal element is connected to a crystal filter to bypass signals of a predetermined frequency which are applied through the filter. The shunt connected crystal element can be used with a bandpass filter to bypass frequencies at which the crystal filter produces a spurious response so that such frequencies will not appear in the filter output. Alternatively, the monolithic element can be selected to bypass frequencies adjacent the edges of a band which is selected, to provide sharp attenuation at the edges of the band thereby providing a very steep filter characteristic. The monolithic element includes a flat quartz wafer with electrodes provided on both sides at two separate portions of the wafer to form two resonant portions coupled through the wafer. The electrodes of one portion are connected across the input or the output of the crystal filter, and both electrodes of the other resonating portions are grounded.

摘要： A two-pole monolithic piezoelectric filter (50) provides an improved frequency response at specified frequencies above the center frequency of a two-pole filter; at these frequencies the frequency response exceeds the attenuation of a four-pole filter without any increase in space, volume, or cost by the inclusion of additional resonator stages (64 and 68) formed into the substrate (52). Appropriate selection of the dimensions of these resonator stages can be used to adjust the frequency at which these resonator stages provide additional desired attenuation.

摘要： A semiconductor substrate with electronic circuitry (e.g., a transmitter or receiver) formed thereon and including interconnects. A ferrite disk bonded to the substrate so as to interact with the interconnects, when the ferrite disk is activated by a substantially constant magnetic field thereacross, to provide frequency selectivity within the electronic circuitry. A permanent magnet positioned adjacent to the ferrite disk to provide a substantially constant magnetic field across the ferrite disk so that the magnetic field produces resonance in the ferrite disk.

摘要： A method of rotating a non-temperature compensated Bechmann curve of a quartz strip. The method includes the steps of determining (102) whether a crystallographic orientation of an AT cut quartz strip is within a desired specification; selecting (104) a predetermined nominal electrode coverage having a nominal electrode width for an in-specification AT cut quartz strip; and tuning (106) an out of specification crystallographic orientation, by: adjusting (108) the electrode width with respect to the nominal electrode width, to bring the out-of-specification crystallographic orientation of an out-of-specification AT cut crystal quartz to within a desired specification having an in-specification Bechmann curve with an inflection point; and rotating (110) an out-of-specification Bechmann curve about the inflection point to substantially approach the desired in-specification Bechmann curve.
