“…If DW is to impact RF circuits, then switches will need to be developed, such as MEMS or phase change materials that can act as reconfigurable electronics for phased array applications [125,126]. Moreover, some new works are coming out on printed magnetic materials that could be viable for use as inductors or circulators that will enable further miniaturization of printed microelectronics since these have been difficult to fabricate with traditional thin film growth techniques with high permeability (μ) over high frequencies [127].…”

Printing methods such as additive manufacturing (AM) and direct writing (DW) for radio frequency (RF) components including antennas, filters, transmission lines, and interconnects have recently garnered much attention due to the ease of use, efficiency, and low-cost benefits of the AM/DW tools readily available. The quality and performance of these printed components often do not align with their simulated counterparts due to losses associated with the base materials, surface roughness, and print resolution. These drawbacks preclude the community from realizing printed low loss RF components comparable to those fabricated with traditional subtractive manufacturing techniques. This review discusses the challenges facing low loss RF components, which has mostly been material limited by the robustness of the metal and the availability of AM-compatible dielectrics. We summarize the effective printing methods, review ink formulation, and the postprint processing steps necessary for targeted RF properties. We then detail the structure-property relationships critical to obtaining enhanced conductivities necessary for printed RF passive components. Finally, we give examples of demonstrations for various types of printed RF components and provide an outlook on future areas of research that will require multidisciplinary teams from chemists to RF system designers to fully realize the potential for printed RF components.

t here is an increasingly high demand for compact, low-loss reconfigurable filters in various advanced wireless applications: cognitive radios, modern transceivers, and antijamming communication systems, to name a few [1]. With reconfigurable filters, wireless communication systems that require multiple operating frequency bands can be implemented in a smaller size and at a reduced cost compared to conventional systems using multiple single-frequency filters. Bandpass filters provide a better RF performance compared to low-pass or high-pass filters, resulting in improved signal-to-noise ratio and out-of-band performance [2].Several designs have been reported for implementing tunable or reconfigurable filters. the frequency tuning for such devices is achieved electronically by technologies such as solid-state varactors or switches [3], RF

“…Very recently, phase change materials (PCM), as GeTe chalcogenide alloy have been evaluated to develop RF switches since they presents a high resistance in the amorphous state and low resistance in the crystalline state [9] [10]. Our paper presents the integration of Ge2Sb2Te5 (GST) phase change material for the realization of RF/microwave switches.…”

This paper presents the design, fabrication and characterization of Ge2Te2Sb5-based phase change material RF switches. The material exhibits non-volatile reversible amorphous to crystalline phase change with resistivity changes up to 105 orders of magnitude. Being non-volatile, these RF switches do not require permanent bias to be maintained in a given state. We present the design of a 4-terminal RF switch integrating an indirect heating system to induce amorphous to crystalline phase change of the material. The measured figure of merit FOM (Ron× Coff) is about 450 fs, which is comparable to FOM obtained for SOI and SOS technologies, without permanent bias.
