RISModeling of a novel low-noise, low-impedance, micro-mechanical, mixer filter for use in cell phones
frequency down-conversion (mixing) and highly selective low-loss filtering of applied electrical input signals. Using this single device, translation of an input radio frequency (RF) signal to a 71 MHz intermediate frequency (IF) and subsequent high-Q band...
Determining RF MEMS Switch Parameters by Neural Networks
A challenge in designing a RF MEMS switch is the
determination of its parameters to satisfy the application
requirements. Often this is done through a set of comprehensive
time consuming simulations. This paper employs neural...
