  • Filter with integrated loading capacitors
    Patent number: 8547188
    Abstract: There is provided an improved filter having resonators substantially disposed between conductive planes which form one or more loading capacitors that are in turn coupled to the resonators. Further, inclusion of a designed void or slot in one or more of the conductive planes allows for control of an introduced transmission zero to manipulate the performance of the filter to achieve desired results, such as improved skirt performance.
    Type: Grant
    Filed: February 23, 2009
    Date of Patent: October 1, 2013
    Assignee: TDK Corporation
    Inventors: Steve Plager, Lothar Johannes Musiol
  • Balanced-output triplexer
    Patent number: 7880562
    Abstract: A balanced-output triplexer includes: a first filter provided between an input terminal and a pair of first balanced output terminals; a second filter provided between the input terminal and a pair of second balanced output terminals; and a third filter provided between the input terminal and a pair of third balanced output terminals. Each of the first to third filters has a pair of output resonators that are interdigital-coupled to each other and connected to the corresponding pair of balanced output terminals.
