RF

RF circuit and device performance is characterized by metrics distinct from those used for digital logic, including gain, noise figure, linearity (often expressed as third-order intercept point), and impedance matching quality, each reflecting a different aspect of how well an RF component actually processes a high-frequency signal rather than simply switching between two logic states. These RF-specific performance metrics directly shape RF semiconductor device and circuit design priorities, since optimizing purely for digital-style metrics like switching speed or power consumption would not capture what actually matters for RF signal processing performance.
