Abstract
In an embodiment, a method of testing a radio frequency integrated circuit (RFIC) includes generating high frequency test signals using the on-chip test circuit, measuring signal levels using on-chip power detectors, and controlling and monitoring the on-chip test circuit using low frequency signals. The RFIC circuit is configured to operate at high frequencies, and an on-chip test circuit that includes frequency generation circuitry configured to operate during test modes.
