摘要： Die Erfindung beschreibt eine Filteranordnung aus einem Bandpassfilter und einem Notch-Filter. Die Kopplung eines Notch-Filters, der aus einem Kondensator und einer Induktivität besteht, mit einem Bandpassfilter aus Resonatoren bewirkt eine bessere Unterdrückung außerhalb des Durchlassbandes.
Durch Verwendung von Dünnschichttechniken können beide Filter bei geringem Raumbedarf auf einem Substrat (1) hergestellt werden. Außerdem wird ein Sender, ein Empfangsgerät, ein Mobilfunkgerät und ein drahtloses Datenübertragungssystem mit einer solchen Filteranordnung sowie Verfahren zur Herstellung einer solchen Filteranordnung offenbart.

摘要： An intermediate frequency filter for an intermediate frequency used in the receiver section of a digital radio communications apparatus is composed of an amplitude-flat ceramic filter incorporating two ceramic resonators, a buffer means and a single tuning circuit having the center frequency thereof within the bandwidth of the amplitude-flat ceramic filter, all being connected in series with each other. The center frequency of the single tuning circuit and Q are adjusted to approximate the amplitude characteristic of the intermediate frequency filter to that of TBT filter (0.4

摘要： A ceramic resonator having a piezoelectric ceramic platelet (10) has electrodes (11a to 11d) on opposite main surfaces separated by the thickness (t) of the platelet. Intermediate its opposite longitudinal ends is a narrower width (W') portion of the platelet (10), of width (W') narrower than the width (W) at those opposite longitudinal ends. At leastthe narrower width portion is poled (14) in the thickness direction of the platelet (10). Thin film metal material forms first to fourth electrodes (11a to 11d). The narrower width portion is sandwiched between parts of the first (11a) and second (11b) electrodes.

The piezoelectric vibrator has favorable characteristics and is free from unwanted resonance of a frequency near the principal vibration resonance frequency attributed to the width dimension. The piezoelectric vibrator comprises a vibration element portion (1) such that the ratio W/H of the width W of the vibration element portion (1) to the thickness H thereof ranges from 2.0 to 4.0, from 4.3 to 5.7, from 6.2 to 7.8, or from 8.2 to 9.8.

The thickness direction of the vibrator forms angle of 0°±5°. The longitudinal direction of vibrator lies, with the X-axis used as a rotation axis, in direction n +57° ±2° clockwise from the Y-axis of the single crystal. A ratio L / H of the length L of the vibrator to the thickness H is not less than 15. A ratio Le / H of the length Le of the exciting electrode to the thickness H of the vibrator element portion is 3 - 6.
