Patent ID: 7256649

Claim:
An intermodulation product reduction system for canceling intermodulation products when amplifying input signals, the intermodulation product reduction amplifier comprising, splitters for respectively receiving the input signals for providing respective inphase and quadrature signals for each of the input signals, phase shifters for phase shifting the quadrature signals for providing phase shifted signals, a first summer for summing the inphase signals for providing a first summed signal, a second summer for summing the phase shifted signals for providing a second summed signal, a first amplifier for amplifying the first summed signal into a first amplified signal, a second amplifier for amplifying the second summed signal into a second amplified signal, and an output hybrid for quadrature phase shifting one of the first and second amplified signals relative to the other and for combining the first and second amplified signals for providing an output signal having the input signals and for canceling the intermodulation products.
