“…It is used to support TDD communication such as in WiMAX and LTE. From the literature, DPDT switches could be designed and used in applications such as phase shifter [10,11], low cost X-band antenna [12], wideband control circuits (attenuators and true time delay elements), Ultra-Wide Band (UWB) applications microwave imaging applications [11], multi-input multi-output (MIMO) system, WLAN [13] and digital cellular handsets [14].…”

“…There are several types of configurations to perform DPDT switching function such as SOI-type (allocating the actuators and the waveguides in separate layers of an SOI wafer) [10], absorptive (four parallel-and cross-connected series transistors) [12], bi-directional [11], reflective [13] and ring [14] configurations. Besides, there is a back to back configuration, where two Single Pole Double Throw (SPDT) switches are connected together as a DPDT switch [9].…”

“…The use of diversity antennas have improved the performance of wireless communication systems as reported in [15][16][17][18]. For switching elements in RF switch (including DPDT switch), researchers used either microelectro-mechanicals (MEMs) [10] or solid state elements such as PIN diode [19] and field effect transistor (FET) [13,14,20]. However, MEMs switches are not suitable for high power applications due to their limited power capabilities [21].…”

Abstract-A novel selectable multiband isolation of Double Pole Double Throw (DPDT) switch with switchable transmission line stub resonators has been proposed for applications of WiMAX and LTE in 2.3 and 3.5 GHz bands. In this paper, two DPDT switch designs are proposed; the first design is a fixed DPDT switch, and the second is a selectable DPDT switch. The second design allows selecting only one band and unselecting the other or selecting both of them. However, the first design does not allow so. The transmission line stub resonator used in this design is an open stub resonator with quarter wave of the electrical length. By using a simple mathematical model, the theory of the transmission line stub resonator was discussed where it can be cascaded and resonated at center frequencies of 2.3 and 3.5 GHz. Moreover, the cascaded transmission line stub resonators can be reconfigured between allpass and bandstop responses using discrete PIN diodes. The key advantage of the proposed DPDT with switchable transmission line stub resonators is a multiband high isolation with minimum number of PIN diodes. Therefore, the simulated and measured results showed less than 3 dB of insertion loss, greater than 10 dB of return loss and higher than 30 dB of multiband isolation in 2.3 and 3.5 GHz bands.

“…The technique for multi-band and multi-functional capabilities using the diode and switch has also been found to be useful in other microwave applications, such as for use with reconfigurable antennas [8,9]. Recently, the diplexer and switch in time-division communications systems were combined into one device, called the switchplexer [10][11][12]. Fig.…”

“…1 shows the concept of the switchplexer [12], which integrates both the switch and the diplexer. The switch can change the signal path between the receiving and transmitting signals, as described in [11,12], or it can change the signal path between the two receiving signals with different bands, as shown in [10]. The diplexer consists of two or more bandpass filters.…”

This paper proposes a reconfigurable microstrip diplexer, also known as a switchplexer, for use with single-switch operation of frequency band and output path. The proposed switchplexer is composed of a rectangular ring resonator and a switch on a shorting pin, which is inserted between the ring resonator and the ground plane. The rotated main current distributions occurring at different switch statuses provide the diplexer's different operating bands and different output ports. The performance of the simply designed switchplexer is successfully demonstrated via simulation and measurement.Key Words: Diplexer, Filter, Reconfigurable Diplexer, Switchplexer.
