摘要： [Problem]
To obtain a variable frequency source that produces high purity signals.
[Constitution]
A serial resonance circuit is prepared. The serial resonance circuit is configured of a pair of resonance elements serially connected to each other at a midpoint therebetween and exhibiting resonance frequencies equal to each other. To both ends of the serial resonance circuit, phase shift circuits that shift phases so that the phases are reverse to each other are connected. A resonance output obtained from the serial resonance circuit when AC power is supplied between the midpoint and an input side of the phase shift circuit is obtained as an external output.

摘要： The present invention provides a filter device constructed of a combined ladder and lattice filter topology. The filter device according to the present invention synergetically combines the good features of both types of filters. Using the filter device according to the present invention an integrated unbalanced-to-balanced filter device can be realized. Accordingly, a substantial decrease in the number of components can be achieved. Furthermore, the filter device according to the present invention can be integrated with further components, preferably active RF-components, on a single chip.

摘要： The invention relates to a dual-mode surface wave filter which can be operated in a symmetrical or asymmetrical manner, comprising tracks (A, B) which are coupled to each other by transformers and interdigital converters for each track arranged inside reflectors and acting as input or output converters. The impedance of the input and/or output converters of the filter is determined by omission or overlapping weighting and/or by dividing the input and output converters according to each acoustic track (A, B) into several at least partially series-connected individual converters (W3-W6).

摘要： Disclosed is an elastic surface wave filter device which can realize balanced operation with a neutral terminal kept at a ground potential, and is adaptable for any system of unbalanced input - balanced output or balanced input - unbalanced output even with an input and an output being different in characteristic impedance from each other. An elastic surface wave filter (3b) having a predetermined phase is cascaded to an elastic surface wave filter (4) having a phase different about 180 degrees from the predetermined phase to form a first set of cascaded elastic surface wave filters. An elastic surface wave filter (3a) having the predetermined phase is cascaded to an elastic surface wave filter (3c) having the predetermined phase to form a second set of cascaded elastic surface wave filters. One of input/output terminals of the first set of cascaded elastic surface wave filters and one of input/output terminals of the second set of cascaded elastic surface wave filters are electrically connected in parallel to an unbalanced input/output terminal (6). The other input/output terminal of the first set of cascaded elastic surface wave filters and the other input/output terminal of the second set of cascaded elastic surface wave filters are electrically connected in series to balanced input/output terminals (9a, 9b).

摘要： A differential-driven transducer consisting of at least one first transducer (5) and a second transducer (6) connected in parallel so that the differential inputs are symmetrical and thus form first and second acoustic channels respectively. The two transducers (5, 6) have a predetermined mutual longitudinal offset. The transducer may be used in mobile radio filters.
