  • Diplexer and multiplexer using the same
    Patent number: 7924116
    Abstract: A diplexer provides a high degree of design freedom for satisfying the requirements of electric characteristics so as to realize desired characteristics and at the same time can be downsized and a multiplexer is realized by using such a diplexer. The diplexer includes a filter having a first pass band and a filter having a second pass band with a frequency band at least twice as high as the frequency band of the first pass band, the filter having the first pass band being a filter of the lumped constant type, the filter having the second pass band being a filter of the distributed constant type.
    Type: Grant
    Filed: January 22, 2008
    Date of Patent: April 12, 2011
    Assignee: NGK Spark Plug Co., Ltd.
    Inventors: Syouji Ono, Tetsuo Suehiro, Jyunichi Ichikawa, Keiji Takagi, Manabu Sato
  • Laminate type band pass filter and diplexer using the same
    Patent number: 7902941
    Abstract: It is possible to generate an additionally attenuation pole in a laminate type band pass filter without adding an attenuation circuit and improve the attenuation characteristics of the laminate type band pass filter by independently controlling the frequencies of the attenuation poles. A diplexer is realized by using at least such a filter.
