“…Recent scientific literature has described several technological options to achieve the tuning of SIW filters [3]. Amongst them, solutions based on piezoelectrical or mechanical technologies [4,5] are not suitable as they cannot match all the constraints induced by our spatial application (size, weight, speed, power consumption, etc.). Thus, a choice was made to design a solution based on electrically-controlled microelectronic devices (diodes, transistors, radio frequency micro-electrical-mechanical systems (RF-MEMS), etc.)…”

This paper presents a digitally tunable SIW (substrate integrated waveguide) filter designed for X-band, based on RF-MEMS (radio frequency micro-electrical-mechanical systems) technology. Four commercial off-the-shelf RF-MEMS single-pole single-throw (SPST) switches were directly mounted on the upper surface of the filter, with metallic tuning posts specifically located within each cavity to define the potential achievable frequency range. Fabricated on standard alumina substrate, the design of the filter and the biasing network enabled fine digital frequency control of up to four functional states by the inclusion of wire bondings between each switch and the substrate. A relative tuning range of 2.3% was achieved between the lower and upper discrete states of 2.76% and 2.89% in the 3 dB fractional bandwidths.

Evanescent‐mode resonators offer a plethora of advantages including high tuning range, quality factor, linearity, and power handling in a mobile form factor. This chapter presents the basic resonator design concept along with advanced tunable RF filters with excellent performance. The versatility of the available couplings also makes evanescent‐mode resonators ideal for many others circuits and systems beyond filters. This article also discusses a number of such circuits that cover a wide frequency range (100 GHz) and high power levels (about 90 W). We review circuits commonly found in receivers (LNAs), transmitters (PAs), and lab‐scale testing (e.g., synthesizers). Evanescent‐mode‐based circuits and systems can be implemented with commercially available low‐cost technologies such as PCB, microfabrication, and injection molding. These features make the presented technology attractive to a wide variety of applications.
