The article details the development and production of an ultra‐wideband discrete single‐pole‐double‐throw (SPDT) Switch, measuring , and functioning within the 23.4–31 GHz frequency range, encompassing 24 and 28 GHz. This switch is specifically engineered to bolster high‐frequency systems in automotive and fifth‐generation applications. Our findings demonstrate that the discrete SPDT switch performs on par with integrated circuits while delivering consistent performance throughout its frequency spectrum. Furthermore, it offers a cost‐effective fabrication process. The switch exhibits an insertion loss ranging from 1.6 to 2.2 dB, with return loss and isolation surpassing 15 and 25 dB, respectively, across the majority of the frequency bandwidths.

In this article, novel architectures for high-speed substrate integrated waveguide (SIW) filtering switches with high-power handling are presented. A four-port filtering doublepole, double-throw (DPDT) switch and a three-port filtering routing switch are demonstrated as a proof-of-concept. For both switches, the structure consists of a main switching circular cavity with concentric posts. These posts enable the excitation of multiple resonant modes. The resonant modes are aligned in frequency using loading capacitances. p-i-n-diodes are used to short loading posts. Consequently, the generated fields interfere constructively and destructively at the output ports. Concept-proving structures are designed, implemented, and measured. For the SIW-DPDT switch, a measured insertion loss and isolation of 2.95 and 26 dB are achieved, respectively, at 7.4 GHz. Furthermore, a 2.98 and 30 dB measured insertion loss and isolation are obtained for the SIW-routing switch, respectively, at 7.7 GHz. The measured insertion losses include the losses of the filtering cavities. The proposed structures share the same switching technique. As a result, the power handling measurements are performed only for the routing switch, which is measured to handle 40 dBm of input power. Also, the employed switching technique is demonstrated to exhibit a switching speed of less than 80 ns.
