A new modulation technique for "LInear modulation with Nonlinear Translation" (LINT) is proposed. The new LINT technique is an extension of the popular LINC (LInear amplification with Nonlinear Components) technique for power efficient transmitter operation with spectrally efficient linear modulations. While providing this advantage, the LINT technique also incorporates the principles of direct modulation and provides frequency translation without the use of multiple stages of bulky upconversion circuitry. These features make the LINT method especially suitable for high frequency applications emerging at upper microwave and millimeter-wave frequencies. A two-stage ×12 frequency multiplier chain is employed for frequency translation, to evaluate the feasibility of the LINT architecture for generating 16-QAM modulation at 28 GHz. The effect of imperfections on modulator performance is also considered.
