The method is based upon both detuning the resonance frequency of the matching network and decreasing the network Q factor by the step-up transformer. Calculations show feasibility of SAW delay line having insertion loss (IL) of 2l dB, 3 dB fractional bandwidth (BW) of 55% and triple transit suppression (TTS) of 62 dB for 3 electrode (N=1) IDT. An exnerimental example shows IL=25 dB, BW-46.5% and TTS=61 dB around at 33 MHz, and confirms the theoretical predictions except for BW. The short IDT launchs spurious bulk modes and bulk longitudinal wave degrades substantially BW.","subitem_description_type":"Other"}]},"item_2_description_15":{"attribute_name":"表示順","attribute_value_mlt":[{"subitem_description":"7","subitem_description_type":"Other"}]},"item_2_description_16":{"attribute_name":"アクセション番号","attribute_value_mlt":[{"subitem_description":"KJ00001511877","subitem_description_type":"Other"}]},"item_2_description_8":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_2_description_9":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_2_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00159741","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_19":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03876055","subitem_source_identifier_type":"ISSN"}]},"item_2_text_7":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Electronics, Tokyo Institute of Polytechnics"}]},"item_2_title_3":{"attribute_name":"論文名よみ","attribute_value_mlt":[{"subitem_title":"A Method of Broad-Band Matching to SAW-IDT (surface acoustic wave interdigital transducer)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"青木, 彪"},{"creatorName":"アオキ, タケシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"152","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"AOKI, Takeshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"62","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-04-21"}],"displaytype":"detail","filename":"KJ00001511877.pdf","filesize":[{"value":"727.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00001511877.pdf","url":"https://kougei.repo.nii.ac.jp/record/37/files/KJ00001511877.pdf"},"version_id":"9fb17aa1-dd2e-487b-a713-8084dce9dea6"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"A Method of Broad-Band Matching to SAW-IDT (surface acoustic wave interdigital transducer)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A Method of Broad-Band Matching to SAW-IDT (surface acoustic wave interdigital transducer)","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["23"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-04-21"},"publish_date":"2017-04-21","publish_status":"0","recid":"37","relation_version_is_last":true,"title":["A Method of Broad-Band Matching to SAW-IDT (surface acoustic wave interdigital transducer)"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T13:46:05.570723+00:00"}
