The Art of Silicon RF Validation: Measuring What a Radio Actually Does

Overview

Validating a wireless system-on-chip is not simply connecting an instrument and recording a number. At RF frequencies, cables, fixtures, interference, instrument limits, and software can become part of the result. This presentation explores how engineers separate true silicon behavior from measurement artifacts while evaluating figures of merit such as noise figure, receiver sensitivity, transmit power, modulation quality, unwanted emissions, interference susceptibility, and radiated performance. Attendees will learn how shielding, calibration, filtering, automation, temperature testing, repeatability, and correlation transform difficult measurements into trustworthy engineering conclusions—and why RF validation remains both an art and a science in practice.

Key Points

• Why a test setup must be validated before conclusions are made about the silicon.
• How receiver, transmitter, emissions, interference, and radiated tests reveal different dimensions of RF performance.
• How calibration, repeatability, automation, and correlation turn individual measurements into trustworthy validation data.
