Cavity Filters Use EM Software
Tue, 09/16/2008 - 11:38am
MtronPTI’s WiMAX cavity filter series utilizes a re-configurable design platform fully modeled in EM (electromagnetic) simulation software in passband center frequencies from 2.30 to 2.70 GHz and a bandwidth range from 0.04% to 0.2% 1 dB. The device allows for use in Rx ?and/or Tx modes and multiple cross-coupling schemes with four transmission zeroes placed on either side of the passband. Modules with two, three, four or six filters of identical or different configurations are available for systems applying MIMO or other antenna diversity technology. Duplexers can be developed using the same re-configurable platform and are offered as a single unit or modules with multiple duplexers. The filter is appropriate for mobile and fixed WiMAX, WiBro and Wi-Fi applications.
