Abstract
We have derived a lumped-element circuit from its coupled line counterpart for a quadrature hybrid coupler. We discuss the uses, design, and characteristics of such circuits in CMOS technology. We show measured characteristics of an example 50-/spl Omega/ 2-GHz coupler with 65 dB of image rejection, 22 dB of directivity, and a 4.7-dB noise figure.Keywords
