Abstract
There is a need for an inexpensive, high-performance, fully-integrable, multi-standard transceiver, which suppresses spurious noise signals. The invention provides a topology that satisfies this need, using a first signal generator which produces an oscillator signal fand a second signal generator which produces a mono-tonal mixing signal φ, where fis a multiple of the frequency of φ; and a logic circuit for generating a multi-tonal mixing signal φ, where φhas significant power at the frequency of said local oscillator signal being emulated, neither of said cpnor said φhaving significant power at the carrier frequency of said input signal x(t) or said LO signal being emulated.
