Patent ID: 8229377

Claim:
A communications device comprising: first output stage circuitry configured to generate a first radio frequency (RF) output signal in response to receiving an RF input signal; a first antenna port configured to couple to a first antenna and configured receive the first RF output signal from the first output stage circuitry; second output stage circuitry configured to generate a second RF output signal in response to receiving the first RF output signal; and a second antenna port configured to couple to a second antenna and configured to receive the second RF output signal from the second output stage circuitry; wherein the first output stage circuitry, the first antenna port, the second output stage circuitry, and the second antenna port are at least partially integrated on the same integrated circuit, wherein the first output stage circuitry is configured to present a first impedance to the first antenna, and wherein the second output stage circuitry is configured to present a second impedance to the second antenna that differs from the first impedance.
