The paper discusses the design aspects of capacitive RF MEMS Symmetric Toggle Switch (STS) with particular emphasis on device compactness, reliability, and improvement in isolation & insertion loss by incorporating hafnium dioxide (HfO2) as a dielectric material. The major impact of the change from SiO2 to HfO2 having dielectric constant of 20, is the reduction in overall dimensions of the swit...

T his paper reports the performance of several broadband SiGe monolithic microwave control circuits suitable for phased array radar applications. The amplitude and phase control MMICs are based on an optimized SiGe PIN diode fabricated using the IBM 5-HP SiGe foundry process. Utilizing this diode, several control circuits were designed, including a broadband (1-20 GHz) monolithic SPDT switch, a...

A hybrid switching node structure with light and microwave links is proposed, which is applicable to the future data relay satellite systems, aiming at the development trend of coexistence of lightlink and microwave-link in the future. An experimental system for the light and microwave hybrid switching node based on wavelength selective optical switches (WSS) and optical transceiver modules, is...

We propose an implementation of a quantum router for microwave photons in a superconducting qubit architecture consisting of a transmon qubit, SQUIDs and a nonlinear capacitor. We model and analyze the dynamics of operation of the quantum switch using quantum Langevin equations in a scattering approach and compute the photon reflection and transmission probabilities. For parameters correspondin...
