Abstract: An integrated circuit (IC) is provided. The IC includes an RF transmitter and an RF receiver. The RF transmitter is configured to generate an RF signal in response to an analog test signal from a test signal generator of a module circuitry that is external to the IC. The RF receiver is configured to generate an outgoing signal according to an input RF signal, and to report the outgoing signal to the module circuitry. The module circuitry performs a test analysis on the RF signal generated by the RF transmitter or on the outgoing signal generated by the RF receiver to determine a test result. The test result is reported to a test equipment having no RF instruments.

Abstract: An integrated circuit (IC) is provided. The IC includes: a controller, a serializer-deserializer (SerDes) device, a transmitter, and a receiver. The controller is configured to obtain a test signal when the IC has entered a test mode. The SerDes device is configured to perform a serialization/deserialization process on the test signal. The transmitter is configured to generate a radio frequency (RF) signal in response to the test signal after the serialization/deserialization process. The RF receiver is configured to receive the RF signal in the test mode. The controller further captures the received RF signal from the receiver for determining a test result.
