| Summary: | In this paper, a design comparison of RF SPDT switch with switchable resonators for WiMAX and LTE in 3.5 GHz was reported and discussed. Four SPDT switch designs were compared to each other in terms of isolation, return loss, insertion loss, number of utilised PIN diodes, and absorptive feature. The first SPDT switch design, Design 1, used a two-cascaded switchable transmission line stub resonators. The second, Design 2, utilised a two-cascaded switchable radial stub resonators. The third, Design 3, was based on three-cascaded switchable parallel coupled lines and a single radial stub resonator. Design 4 was based on three-cascaded switchable rings and a single radial stub resonator. As a result, Design 4 showed a very good simulated and measured isolation, return loss and insertion loss at the operation frequency of 3.5 GHz. Besides, Design 4 resulted with the highest isolation with an absorptive feature. |
