[分享] Full Wave Analysis and Design of RF Tunable Filters

  Abstract一In this paper, a systematic design method for
the finline structure tunable filter is presented Eased on Flter
synthesis  and  the  full  wave  analysis  using  Ansoft EM
simulation software HFSS. The varactor effects have been
discussed. Two filter examples, one in Ka- and the other in K-
band, . are  built  and  tested  to  verify  the  design.  The
measurement results are in agreement with the simulations.
