Abstract

Switchable function of reconfigurable feeding network and Single Pole Double Throw (SPDT) switch related to WiMAX application is proposed in this paper. Positive Intrinsic Negative (PIN) diode is used to realize switchable function and the operating frequency for power divider and SPDT switch. At the output ports, PIN diodes are added for SPDT switch function by turning on and off the output port. Then, the stub is added at the output port for matching when the function of the power divider is changed to SPDT switch. Rogers RO4350 (er = 3.48, h = 0.508mm) is used as a substrate material and the copper (thickness = 0.035 mm) related to patch of this proposed design. The simulation results for power divider at both frequencies are S11 less than -25 dB. The insertion loss, S12 and S13, for power divider at 2.5 GHz and 3.5 GHz are - 3.733 dB and -3.634 dB respectively. Meanwhile, the simulation results for SPDT switch showed that the S11 is less than -15 dB; S12 and S13 are better than -2 dB and infinity isolation for S23 and S13 for both WiMAX frequencies. Based on the simulation results, power divider and SPDT switch were well applied where it has better return loss with less than -25 dB and -15 dB respectively. The proposed design realized a switchable function which can perform as either reconfigurable power divider or SPDT switch by using PIN diodes and it can be used for power amplifiers or antenna array applications.
