Abstract

Although mixer design is often viewed as a mature technology, there seems to be no end to the supply of creative new ideas for mixer circuits, or for new needs. Today, the needs of system designers are evolving from high-performance circuits to low-cost, manufacturable, and integrable designs. This particularly true of mixers for wireless, cellular, and other modern communication systems. In this paper we review the work in this area and examine some of the directions it can—and perhaps should—take.
