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 108 phase unbalance.

Abstract
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 108 phase unbalance.File in questo prodotto:
