Abstract

Single Pole Double Throw switch (SPDT) is one type of the radio frequency (RF) switch is used for time division duplex (TDD) system which it can reduce the problem between transmitting and receiving process. High isolation value between the transmitter and receiver in the RF front end system is an important parameter in the design SPDT switch, especially for high power applications. Futhermore, the insertion loss and return loss also the parameters that need to be consider in the SPDT switch design. Therefore, this project work introduced the SPDT switch design using switchable resonator to get the higher isolation, great insertion loss, and higher return loss. The microstrip resonator by using transmission line stub resonator and discreate PIN diode were selected in this SPDT switch design. The project of SPDT switch will be designed for the applications at 5GHz in wireless frequency front-end system. The example of application that operate at 5Ghz such as WiFi and WLAN. These SPDT switch projects should get the isolation value higher than 30dB to avoid any problems between the transmitter and receiver. In addition, the return loss should be more than -10dB and insertion loss should get value almost to 0
