{ "inLanguage": { "alternateName": "eng", "@type": "Language", "name": "English" }, "description": "<p>A very low-loss micromachined waveguide bandpass filter for use in D-band (110–170GHz) telecommunication applications is presented. The 134–146GHz filter is implemented in a silicon micromachined technology which utilises a double <br>\nH-plane split, resulting in significantly lower insertion loss than conventional micromachined waveguide devices. Custom splitblocks<br>\nare designed and implemented to interface with the micromachined component. Compact micromachined E-plane bends connect the split-blocks and DUT. The measured insertion loss per unit length of the waveguide technology (0:008–0:016dB=mm) is the lowest reported to date for any micromachined waveguide at D-band. The fabricated 6-pole filter, with a bandwidth of 11:8GHz (8:4%), has a minimum insertion loss of 0:41dB, averaging 0:5dB across its 1dB bandwidth, making it the lowest-loss D-band filter reported to date in any technology. Its return loss is better than 20dB across 85% of the same bandwidth. The unloaded quality factor of a single cavity resonator implemented in this technology is estimated to be 1600.</p>", "license": "http://creativecommons.org/licenses/by/4.0/legalcode", "creator": [ { "affiliation": "KTH", "@type": "Person", "name": "Campion, James" }, { "affiliation": "KTH", "@type": "Person", "name": "Glubokov, Oleksandr" }, { "affiliation": "KTH", "@type": "Person", "name": "Gomez, Adr\u00edan" }, { "affiliation": "KTH", "@type": "Person", "name": "Krivovitca, Aleksandr" }, { "affiliation": "KTH", "@type": "Person", "name": "Shah, Umer" }, { "affiliation": "Ericsson", "@type": "Person", "name": "Bolander, Lars" }, { "affiliation": "Ericsson", "@type": "Person", "name": "Li, Yinggang" }, { "affiliation": "KTH", "@type": "Person", "name": "Oberhammer, Joachim" } ], "headline": "An Ultra Low-Loss Silicon-Micromachined Waveguide Filter for D-Band Telecommunication Applications", "image": "https://zenodo.org/static/img/logos/zenodo-gradient-round.svg", "datePublished": "2018-10-15", "url": "https://zenodo.org/record/1462691", "keywords": [ "D-band", "bandpass filter", "micromachined waveguide", "waveguide filter", "wireless link", "telecommunication" ], "@context": "https://schema.org/", "identifier": "https://doi.org/10.1109/MWSYM.2018.8439601", "@id": "https://doi.org/10.1109/MWSYM.2018.8439601", "@type": "ScholarlyArticle", "name": "An Ultra Low-Loss Silicon-Micromachined Waveguide Filter for D-Band Telecommunication Applications" }
