摘要： A surface acoustic wave filter is provided which performs balanced signal/unbalanced signal conversion. The input and output impedances are different from each other. In a surface acoustic wave filter of the longitudinal mode type, a signal is applied to two terminals of an input interdigital transducer, or a signal is output from two terminals of an output interdigital transducer, thereby consituting a balanced type filter. The aperture length of the input interdigital transducer is different from that of the output interdigital transducer.

摘要： 36.degree. -rotated Y-cut X-propagation lithium niobate substrate (LiNbO.sub.3) was used as a piezoelectric substrate to compose a surface acoustic wave filter and is connected with a dielectric filter in series. The dielectric filter having a sign of the frequency temperature characteristic which is opposite to that of the surface acoustic wave filter was used. Accordingly, a high frequency filter, comprising a surface acoustic filter and a dielectric filter connected in series, which can secure sufficient attenuation without an increase in the insertion loss within the band can be provided.

A transmitting interdigital transducer and a receiving interdigital transducer are formed on a substrate comprising 41.degree. Y cut-X propagation lithium niobate. A balanced type surface acoustic wave filter is formed on a substrate comprising 36.degree. Y cut-X propagation lithium tantalate. The balanced type surface acoustic wave filter comprises two series-arm surface acoustic wave resonators and two crossed-arm surface acoustic wave resonators connected in a lattice. The substrate on which the transmitting interdigital transducer and the receiving interdigital transducer are formed and the substrate on which the balanced type surface acoustic wave filter is formed are located in a ceramic package. One of the input terminals of the transmitting interdigital transducer is grounded. The output terminals of the receiving interdigital transducer are connected to the input terminals of the balanced type surface acoustic wave filter.

摘要： A surface acoustic wave filter having a configuration in which a plurality of series surface acoustic wave resonators and parallel surface acoustic wave resonators are connected is used as a receiving filter included in a receiving circuit of a communication apparatus capable of simultaneously transmitting and receiving signals. When the transmitting frequency is higher than the receiving frequency, one of the parallel surface acoustic wave resonator, connected between the signal line and the ground, is disposed most closely to the input terminal of the filter. When the transmitting frequency is lower than the receiving frequency, one of the series surface acoustic wave resonator, connected in series to the signal line, is disposed most closely to the input terminal of the filter. Accordingly, the singular point of the filter is prevented from coinciding with the transmitting frequency, so that the deterioration of the resonator is prevented.

摘要： This invention provides a surface acoustic wave device mounted module which is miniature, light, and highly reliable. The surface acoustic wave device mounted module also has excellent frequency characteristics. The surface acoustic wave device mounted module includes a multilayer substrate which has at least one layer of a shield pattern, input-output electrodes, grounding electrodes, through holes used for connecting electrodes, and a surface acoustic wave element. The surface acoustic wave element has metallic bumps, which are transfer-coated with a conductive resin, on electrode pads and an insulating resin around the surface acoustic wave element. The electrode pads are input-output terminals and grounding terminals formed on the surface acoustic wave element. Continuities between the input-output terminals and the input-output electrodes, and between the grounding terminals and the grounding electrodes are established by the through holes. An electrode pattern is formed on the surface of the multilayer substrate facing and surrounding the surface acoustic wave element. A metallic lid is attached to the electrode pattern by a solder or a conductive resin so that the surface acoustic wave element is sealed in an airtight condition. The electrode pattern is connected to the grounding electrodes by the through holes.
