“…For the switching element, PIN diodes were utilised in most research works. To integrate BPF with SPDT switch in a one device, several techniques were used such as dielectric resonators (DRs) [15], LC resonators [11], SISL [30], and common shorted stepped-impedance resonator (CSSIR) [25]. While the output of the first nine listed studies depicted low insertion and high isolation, they suffered from low return loss at OFF-port; in other words, they did not provide an absorptive feature as created in [25].…”

“…Filter-integrated switch (FIS) as depicted in Figure 1 is another integrated/multifunction device. From the year 2006 onwards, numerous studies have reported filter-integrated double pole double throw (DPDT) switch [5], single pole single throw (SPST) switch [6][7][8], and SPDT switch [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. In order to produce FISs and integrate BPF with SPDT switch in one device, several techniques have been used, such as dielectric resonators (DRs) [15], LC resonators [11], substrate integrated suspended line (SISL) [30], and common shorted stepped-impedance resonator (CSSIR) [25].…”

In this paper, an absorptive filter-integrated switch (FIS) using switchable T-shape resonators is presented. The FIS was made up of two absorptive T-shape resonators and integrated with single pole double throw (SPDT) switch. A simple mathematical analysis of isolation and insertion loss of filter-integrated SPDT switch is discussed. PIN diodes were used as the switching elements for the SPDT switch and to reconfigure between the band-stop and bandpass responses. The proposed absorptive FIS design could be used for internet of things (IoT) applications such as Zigbee and Bluetooth at an operation frequency of 2.45 GHz. As a result, the proposed FIS exhibited low magnitude of insertion loss and high isolation. Therefore, the key advantages of the proposed FIS design are low insertion loss, high isolation, and good return loss at both ON-and OFF-state ports.

In this paper, a reconfigurable ring resonator-based filter integrated switch (FIS) was presented. The FIS was made up of two absorptive ring resonators, reconfiguring between band-stop and band-pass responses, and integrated with single pole double throw (SPDT) switch. A simple mathematical analysis of isolation and insertion loss of filter-integrated SPDT switch was discussed. PIN diodes were used as the switching elements for the SPDT switch and to reconfigure between the band-stop and band-pass responses. The proposed absorptive FIS design could be used for wireless data communication systems such as Zigbee and Bluetooth at an operation frequency of 2.45 GHz. As a result, the proposed FIS exhibited 2 dB of insertion loss and better than 38 dB of isolation. Therefore, the key advantages of the proposed FIS design are low insertion loss, high isolation and good return loss at both ON-and OFF-state ports.

“…For example, transistors can be utilized to switch ON and OFF two filters which are connected by T junction to realize the millimeter-wave filtering SPDT switches [1], [2]. In [3], the capacitively coupled LC resonators with loaded PIN diodes are used to develop the filtering SPDT switch with compact size. Besides, the filtering SPDT switches have also been presented with compact size, low loss, or wide stopband performance in [4] and [5].…”
