Abstract

In wireless data communications using Time Duplex Division (TDD), Single Pole Double Throw Switch (SPDT) Switch is used to switch between transmit mode (Tx) and receive mode (Rx) in RF front-end system. The SPDT switch is used in Modern Wireless Communication Systems. So far, existing application switch does not have a dual function between isolation improvement and bandstop feature in Single Pole Double Throw Switch (SPDT) Switch because the main parameter of RF Switch is focusing on isolation performance. In order to achieve the dual function between isolation improvement and bandstop feature in SPDT switch, we use a switchable resonator. The switching element that we use is PIN diode. The advantage of this technique is to reduce of size of the circuit with minimum usage of switching elements compared to the technique using multiple PIN diodes. The design involves simulation using Advance Design System (ADS) software 2011 and fabricated using FR4 board. The S-parameters of the switch are analyzed in the ADS software. The circuit of the switch is designed as layout in ADS software and prepare for fabrication process. Measurement is necessary for verification with simulation results. Both simulated result and measurement result were successfully achieved high isolation performance of more than 30dB with minimum number of PIN didoes
