Patent number: 10256926Abstract: The present disclosure provides a method for configuring a communication system with a variable attenuator. The method includes measuring a first attenuation accuracy of the communication system at a first attenuation rate of the variable attenuator, and setting the variable attenuator based on the first attenuation accuracy so that the variable attenuator has a second attenuation rate and the communication system has a second attenuation accuracy. The method further includes obtaining a plurality of first gains at first temperatures and first frequencies, and performing an interpolation process to obtain, from the plurality of first gains, a plurality of second gains at second temperatures and/or second frequencies. The method also includes building a three-dimensional gain table with respect to the temperature, the frequency and the attenuation rate.Type: GrantFiled: April 2, 2018Date of Patent: April 9, 2019Assignee: MICROELECTRONICS TECHNOLOGY, INCInventors: Ruei-Yuen Chen, Hsiang-Hao Sung

Patent number: 7570496Abstract: An electromagnetic interference shielding apparatus for a signal transceiver employs two folded-edge mechanisms coupled together and an adhesive. The electromagnetic interference shielding apparatus includes a metal cover, a chassis having a waveguide output hole, and an adhesive. A first combination portion having a first curved section is disposed on an edge of the metal cover. A second combination portion having a second curved section corresponding to the first combination portion is disposed on an edge of the chassis. The adhesive is used to combine the first combination portion and the second combination portion. The waveguide output hole outputs a signal transmitted by the signal transceiver. The first combination portion and the second combination portion form a curved space that is used with the adhesive to prevent leakage of the transmitted signal and the interference of external noises.Type: GrantFiled: August 30, 2007Date of Patent: August 4, 2009Assignee: Microelectronics Technology Inc.Inventors: Ruei Yuen Chen, Fang Yu Kuo, Yi Hsiang Huang
