“…The comparison was made at the center frequency of 25.875 GHz in the 26 GHz band for 5G millimeter wave communications. Therefore, the proposed SPDT switch design could be integrated with other millimeter wave sub-components such as antenna array [26], [27], bandpass filters [28], [29] and power amplifers [30], [31] for a complete system design of 5G millimeter wave communications as depicted in Figure 1.…”

A single pole double throw (SPDT) discrete switch design using switchable substrate integrated waveguide (SIW) resonators is proposed in this paper. It was designed for the millimeter wave multiple input multiple output (MIMO) transceiver. An example application is for 5G communication in 26 GHz band. High isolation between transmitter and receiver (in the transceiver) is needed in SPDT switch design to minimize any high radio frequency (RF) power leakage in the receiver. Therefore, the use of switchable SIW resonators can achieve higher isolation if compared to the conventional series SPDT switch, where the isolation of the proposed SPDT is depend on the bandstop response of the SIW resonators. The switchable SIW resonators can be switched between allpass and bandstop responses to allow the operation between transmit and receive modes. As a result, the simulation and measurement showed that the proposed SPDT switch produced an isolation higher than 25 dB from 24.25 to 27.5 GHz compared to the conventional design.

“…Ca and Cb represent the parasitic capacitance within the transmission lines and port 1 and 2 are the input and output nodes, respectively. In order to calculate their resonance frequencies without considering the impedance matching network effect, the output port is assumed to be an open circuit [20]. The input admittance of the schematic illustrated in Figure 2a can be calculated as:…”

“…To further reduce the length, the slow-wave structures [10,11] and the co-planar waveguide (CPW) [12,13] are proposed though the overall size is still relatively large. In recent years, the coupled transmission lines based resonator is extensively explored due to its compact size [14][15][16][17][18][19][20][21][22][23][24][25][26][27]. It makes use implementing the transmission zeros at the required frequency.…”

In this work, the design of a novel Ka-band miniaturized bandpass filter with broad bandwidth is demonstrated by using inversely coupled U-shaped transmission lines. In the proposed filter, two transmission zeros can be generated within a cascaded U-shaped structure and it can also be proven that, by inversely coupling two stacked U-shaped transmission lines, the notch frequency at the upper stopband can be shifted to a lower frequency, which results in a smaller chip size. The key parameters affecting the performance of the proposed filter are investigated in detail with the effective lumped-element circuit illustrated. Fabricated in a 0.13-μm SiGe BiCMOS process, the proposed filter achieves an insertion loss of 3.6 dB at a frequency of 28.75 GHz and the measured bandwidth is from 20.75 GHz to 41 GHz. The return loss is better than −10 dB from 20.5 GHz to 39 GHz. The lower transmission zero is located at 11.75 GHz with a suppression of 54 dB while the upper transmission zero is around 67 GHz with an attenuation of 34.6 dB. The measurement agrees very well with the simulation results and the overall chip size of the proposed filter is 176 × 269 μm2.

“…3 In addition, metamaterial based wide bandwidth bandpass filters have already attracted considerable attention. 4,5 Several prior works can be found in the literature on bandpass filters utilizing silicon, [15][16][17][18][19][20][21][22][23][24][25][26][27][28] GaAs, [29][30][31] LTCC, 32,33 and MEMS [6][7][8][9][10][11][12][13][14][34][35][36][37][38][39][40][41][42][43][44] technologies. However, due to the larger fabrication tolerances of the LTCC process, it is not quite suitable for the mass production of these circuits at millimeter-wave frequencies.…”

In this work, radio frequency (RF) micro-electromechanical system (MEMS)based frequency and bandwidth tunable bandpass filter is presented for application in 24 GHz Doppler radar transceivers. The filter is fabricated on 635 μm alumina substrate using surface micromachining process. Total area of the filter is only 2.8 mm 2 excluding bias lines and pads. Functional building blocks of the proposed filter are fabricated and tested independently to ensure optimum filter responses. The proposed filter can be tuned to any frequency between 22 and 24 GHz based on electrostatic actuations. It demonstrates insertion loss of 1.67 dB and matching of 18.6 dB at 24 GHz with fractional bandwidth of 6.5%. Filter gives acceptable matching over a 5 GHz bandwidth (21.65-26.65 GHz) with an average insertion loss of 4.7 dB. Filter works satisfactorily up to 10 billion cycles with 0.1 to 1 W of RF power. To the best of our knowledge, this is the first reported tunable MEMS bandpass filter at 24 GHz with 10 billion cycles reliability and with 1 W of RF power for radar applications.
