Design Of Hybrid RF Diplexer And Triplexer For Multiband WiMAX Application
Radio frequency (RF) diplexer and triplexer are widely used in wireless communication system. The development of RF diplexer and triplexer are very competing in multiband Worldwide Interoperability for Microwave Access (WiMAX) application. This is due to the high demands of wireless communication sy...

Radio frequency (RF) diplexer and triplexer are widely used in wireless communication system. The development of RF diplexer and triplexer are very competing in multiband Worldwide Interoperability for Microwave Access (WiMAX) application. This is due to the high demands of wireless communication system to support multi-services simultaneously. Many RF diplexer and triplexer are designed using common type of the filter. Besides, the preliminary designs are for multi-applications not specifically for multiband WiMAX application. The multiband WiMAX has been implemented around the globe as allocated by the International Telecommunication Union (ITU). Bandwidth of the multiband WiMAX application are varies depending on the countries. Therefore, the proposed RF diplexer and triplexer are developed to cope with the multiband WiMAX bandwidth.
