| Abstract | One-port SAW resonators with improved temperature stability were suggested by Takagi et al. This solution represents a double resonator of two single resonators on STX quartz the turnover temperatures of which are positioned below and above room temperature, respectively. Coupling of the single resonators is implemented by the waveguide effect. Both the temperature coefficient of frequency of 1st and 2nd order (TCF1, TCF2) are compensated. The purpose of this paper is to present a double one-port SAW resonator the single resonators of which are characterized by using different propagation angles (angle between the propagation direction and the X axis) on one of the ST cuts of quartz in vicinity of the propagation angle where the TCF1 vanishes. The coupling is now achieved by a series connection of two parallel connections of a single resonator and of an inductance. The compensation of the TCF1 and TCF2 is demonstrated by simulations as well as by experiments. The TCF2 can be compensated by choosing the inductances in a suitable manner whereas the TCF1 is compensable by adjusting the inductance ratio. Double resonators on 35.5 degrotY quartz were investigated experimentally |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
