“…However, mature GaAs and CMOS processes are mainly used to design planar circuits, and there are still few publicly reported SIW filter chips, considering the complexity of chip processing rules. Compact and high selectivity SIW BPF MMIC was proposed by using multiple TE101 mode SIW resonators [7,29]. Higher-order mode resonators are introduced in the SIW filter design to achieve high-frequency selectivity [30].…”

This letter presents a fully monolithic microwave-integrated circuit (MMIC) substrate integrated waveguide (SIW) filter using integrated passive device (IPD) technology for Q-band applications. It is challenging to implement an SIW bandpass filter (BPF) at the chip level due to the complex process rules of chip processing. A possible solution is to use multiple TE101 mode SIW resonators to build a BPF via magnetic coupling. However, this layout method can easily cause a larger chip aspect ratio, which is not conducive to the chip's reliability. To this end, the proposed SIW filter adopts four SIW resonators to form a highly selective BPF through planar stacking. Measurement results show that the minimum insertion loss of the proposed SIW filter is 3.07 dB, and fractional BW (FBW) of 4.4 % with a compact size of 0.199𝜆 2 0 , including pad, which is among the best compared to previously reported SIW chip BPFs.
