Claim:
An incompressible receiver for minimizing undesired higher-order nonlinear distortion products comprising: a first receiver path having a first receiver path input configured to receive an input signal having at least one non-baseband frequency, and at least one first receiver path output configured to provide a first path output signal having at least one baseband (BB) frequency, said first receiver path comprising at least one mixer, said at least one mixer having a first input terminal electrically coupled to a local oscillator configured to provide a local oscillator signal and having a second input terminal electrically coupled to said first path input and having a mixer output terminal electrically coupled to said at least one first receiver path output, said mixer configured to perform a frequency conversion, said first receiver path output signal comprising a higher-order nonlinear distortion component; at least a second receiver path having a second receiver path input configured to receive an input signal having at least one non-baseband frequency, and a second receiver path output terminal configured to provide a second receiver path output signal, said second receiver path comprising an odd path including at least one odd-order nonlinear distortion reference component and an even path including at least one even-order nonlinear distortion reference component, each of said at least one odd-order nonlinear distortion reference component and at least one even-order nonlinear distortion reference component being configured to be in an “on” state or in an “off” state independent of any other of said at least one odd-order nonlinear distortion reference component and at least one even-order nonlinear distortion reference component, and at least one mixer configured to combine an even-order reference signal and an odd order reference signal as said second receiver path output signal; and a combining element configured to receive as input said output signal from said first receiver path output terminal and configured to receive as input said output signal from said second receiver path output terminal and configured to combine said input signals such that the higher-order nonlinear distortion signals are substantially attenuated at an output of said combining element.
