RF chips are crucial components in wireless communication systems, and their performance directly impacts the reliability of the entire communication link. This article will systematically introduce three key technologies for RF chip testing: switch time, harmonics, and intermodulation distortion. We will also compare laboratory verification with mass production testing. 1. Switch Time Testing for RF Chips Switch time is a critical parameter to measure the response speed of RF chips, specifically referring to the time it takes for the signal power to stabilize at 90% during the transition from “on” to “off” or vice versa. This parameter is essential for RF chips in frequency division duplex (FDD) and time division duplex (TDD) systems.
