Abstract:
A radio frequency (RF) communications device is provided. The RF communications device includes transmitter circuitry configured to generate a calibration signal on a signal line coupled to an antenna port in a calibration mode of operation and an RF output signal for broadcast across the antenna port subsequent to the calibration mode of operation, tuning circuitry coupled to the signal line and configured to receive the calibration signal, and a controller configured to adjust a signal level of the calibration signal generated by the transmitter circuitry and a tuning of the tuning circuitry during the calibration mode of operation. The transmitter circuitry, the tuning circuitry, and the controller are at least partially integrated on the same integrated circuit.
