In this work, a new design method is presented for the design of wide‐band harmonic self‐oscillating mixers (HSOM) with high conversion gain. The optimum design for the HSOM circuit is obtained using bifurcation analysis‐ and control‐techniques in combination with nonlinear optimization techniques based on the use of an auxiliary generator. The design method is illustrated through the design of an 11.25–1.5 GHz third harmonic self‐oscillating mixer (3HSOM) with a 6.5 dB down‐conversion gain over a 1.6 GHz bandwidth. It is also demonstrated how the frequency variation of the conversion gain can be shaped by means of the use of bifurcation control techniques. A good agreement between the simulated and experimental results has been found. Copyright © 2009 John Wiley & Sons, Ltd.
