A new cavity filter series from MtronPTI has been developed especially for WiMAX applications and other wireless metro area network systems. The WiMAX cavity filter series covers the 2.3- to 2.7-GHz frequency range with emphasis on low-loss narrowband systems. A re-configurable design platform fully modeled in electromagnetic simulation software and tested with a stringent design verification process allows for quick delivery of samples that are optimally tuned for specific applications. The passband center frequencies of these devices make them especially well suited to mobile and fixed WiMAX, WiBro, and WiFi applications. The available bandwidth range is 0.04 to 0.2 1 dB. A versatile configuration allows multiple cross coupling schemes with transmission zeroes, placed on either side of the passband and in any combination. Standard housings can be rapidly re-configured to permit reduced lead times for custom applications. Connector locations are flexible and configurable. These devices also feature an integrated low pass filter for excellent extended rejection performance. They can be used in either Rx (radio receive) or Tx (radio transmit) mode. Modules with two, three, four, or six filters of identical or different configurations are available for systems applying MIMO or other antenna diversity technology.
