    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: A wireless transmitter has a digital baseband module and a radio-frequency (RF) transmitter. The digital baseband module generates a multi-mode modulated signal by using a plurality of digital synthesizers. The RF transmitter has a frequency synthesizer and a digital power amplifier (DPA). The frequency synthesizer generates an oscillation signal with an RF carrier frequency. The DPA generates a multi-standard RF signal according to the multi-mode modulated signal and the oscillation signal.
