Aluminum Nitride Two-Dimensional-Resonant-Rods
Xuanyi Zhao, Luca Colombo, Cristian Cassella
In the last decades, Bulk-Acoustic-Wave (BAW) filters have been essential components of 1G-to-4G radios. These devices rely on the high electromechanical coupling coefficient (kt2~…
Reflective Parametric Frequency Selective Limiters with sub-dB Loss and Watts Power Thresholds
Hussein M. E. Hussein, Mahmoud A. A. Ibrahim, Matteo Rinaldi +2
This article describes the design methodology to achieve reflective diode-based parametric frequency selective limiters (pFSLs) with low power thresholds () and sub-dB inse…
Systematic Synthesis and Design of Ultra-Low Threshold Parametric Frequency Dividers
Hussein M. E. Hussein, Mahmoud A. A. Ibrahim, Giuseppe Michetti +3
A new method is discussed for the systematic synthesis, design and performance optimization of varactor-based parametric frequency dividers (PFDs) exhibiting an ultra-low power thr…
Highly-Linear Magnet-Free Microelectromechanical Circulators
Yao Yu, Giuseppe Michetti, Ahmed Kord +6
This paper reports the first demonstration of a magnet-free, high performance microelectromechanical system (MEMS) based circulator. An innovative circuit based on the commutation…
Radio Frequency Magnet-free Circulators Based on Spatiotemporal Modulation of Surface Acoustic Wave Filters
Yao Yu, Giuseppe Michetti, Michele Pirro +6
In this paper, a new generation of magnet-free circulators with high performance is proposed. Circulators are crucial devices in modern communication systems due to their ability t…
