Patent number: 11431320Abstract: An even-mode resonator filter is disclosed. The even-mode resonator filter is provided with high stability, and comprises: a first even-mode resonance module, a second even-mode resonance module, a first filter unit and a second filter unit. In the present invention, the first even-mode resonance module comprises a first resonance unit and a second resonance unit, and the second even-mode resonance module comprises a third resonance unit and a fourth resonance unit. By letting the second resonance unit be coupled to the first resonance unit as well as making the third resonance unit be coupled to the fourth resonance unit, the even-mode resonator filter of the present invention has the advantage of eliminating unexpected resonance.Type: GrantFiled: March 16, 2021Date of Patent: August 30, 2022Assignee: ADVANCED CERAMIC X CORPORATIONInventors: Jyh-Wen Sheen, Chih-Ming Chang

Publication number: 20220116007Abstract: A coupled resonator filter is disclosed. The coupled resonator filter is provided with high quality factor, and comprises: a first resonance unit, a second resonance unit and a main adjustment unit. In the present invention, the main adjustment unit is electrically connected between the first resonance unit and the second resonance unit, and comprises an adjustable capacitor. By changing a capacitance of the adjustable capacitor, a coupling coefficient between the first resonance unit and the second resonance unit is adjusted. As a result, the coupled resonator filter of the present invention included advantages of high controllability of the frequency bandwidth and high inhibition rate of noise signal.Type: ApplicationFiled: February 16, 2021Publication date: April 14, 2022Applicant: ADVANCED CERAMIC X CORPORATIONInventors: Jyh-Wen Sheen, Chih-Ming Chang

Patent number: 9905901Abstract: Differing from conventional directional coupling device being implemented on a coin-like planar board, the present invention stacks a bottom substrate, at least one phase retarding unit, at least one reference ground unit, a coupled circuit layer, a main circuit layer, and a top substrate to form a miniature directional coupling device. Because this miniature directional coupling device not occupies too much circuit area when being applied in a mobile communication product, the miniature directional coupling device can meet the requirements of light weight and compact size demanded by high-technology mobile communications for the electronic components. It is worth explaining that, since the said phase retarding unit consists of many end-to-end connected transmission wires, engineers skilled in designing microwave circuit are able to carry out the modulation of coupling flatness of the miniature directional coupling device by changing a total length of the end-to-end connected transmission wires.Type: GrantFiled: August 31, 2016Date of Patent: February 27, 2018Assignee: ADVANCED CERAMIC X CORPORATIONInventors: Jhin-Ying Lyu, Wei-Jen Lee, Jyh-Wen Sheen

Patent number: 6228788Abstract: Disclosed are ceramic compositions for high-frequency ceramic inductors. The ceramic compositions comprise a mixture of finely divided particles consisting of 20-80% by weight of borosilicate glass and 80-20% by weight of an oxide filler, which can be densified up to 95% at temperatures between 800-1000° C. The ceramic compositions can be processed with organic solvent, polymeric binder and plasticizer to produce green sheets that are co-firable with highly conductive metal such as gold, silver, silver-palladium and copper.Type: GrantFiled: November 30, 1999Date of Patent: May 8, 2001Assignee: Advanced Ceramic X CorporationInventors: Jau-Ho Jean, Shih-Chun Lin
