Patent ID: 7747228

Claim:
A communications device comprising: a first antenna port coupled to a signal line; a second antenna port transmitter circuitry including first output stage circuitry coupled to the signal line and configured to broadcast a first radio frequency (RF) output signal across the first antenna port; second output stage circuitry having an input coupled to the signal line and configured to broadcast a second RF output signal generated from the first RF output signal across the second antenna port; tuning circuitry coupled to the signal line; and a controller configured to provide a set of tuning signals to the tuning circuitry to adjust a tuning of the tuning circuitry and configured to provide a first control signal to the transmitter circuitry to adjust a first signal level of the first RF output signal on the signal line; wherein the controller is configured to provide the set of tuning signals to adjust a capacitance and a resistance of the tuning circuitry, and wherein the first antenna port, the transmitter circuitry, the tuning circuitry, and the controller are at least partially integrated on the same integrated circuit.
