Patent ID: 8903346

Claim:
A system, comprising: a first external mounted amplifier having a first low-noise amplifier coupled to a first antenna, the first low-noise amplifier operable to receive a first signal from the first antenna; a second external mounted amplifier having a second low-noise amplifier coupled to a second antenna, the second low-noise amplifier operable to receive a second signal from the second antenna, wherein the second low-noise amplifier amplifies a second input signal derived from the second signal; a first splitter coupled between the first antenna and the first low-noise amplifier, the first splitter operable to derive a first sampling signal from the first signal; a first phase shifter coupled to the first splitter, the first phase shifter operable to shift the phase of the first sampling signal to create a second cancelation signal; and a second mixer coupled to the first phase shifter, the second mixer operable to mix a second input signal derived from the second signal with the second cancelation signal to create a second output signal.
