Abstract

We propose a nearly all-digital, broadband frequency mixer which synthesizes a sinewave at the frequency difference of two periodic input square waves. The mixer has high output spurious free dynamic range by cancelling the dominant intermodulation products in the sinewave generation process. Due to its use of almost exclusively digital circuitry, it can easily be integrated with CMOS digital circuits. A programmable logic implementation and spectral measurements demonstrate its feasibility and performance.
