An extremely compact Q‐band three‐conductors balun is presented. The proposed structure exploits the increased line‐to‐line coupling to improve bandwidth and impedance transformation. Furthermore the insertion of open‐ended stubs makes the circuit suitable for EHF mixer application. The balun operates in the 38–50 GHz range with a typical 1‐dB amplitude error and 10° phase unbalance. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:1022–1025, 2016
