In this paper, two active‐balun structures based in a differential pair are proposed for the LO and output port of a double‐balanced mixer. A Volterra series approach based on an appropriate nonlinear model for active devices is followed to analyze the baluns, and closed‐form expressions are obtained for the evaluation of the gain and IMD. Criteria for the selection of design parameters are proposed. Results have been compared with alternative nonlinear circuit analysis methods, showing a good correspondence. An MMIC was implemented with HEMTs, demonstrating a good performance up to 10 GHz with a low LO level and power consumption. © 2001 John Wiley & Sons, Inc.
