چکیده
Accompany with the rapid development of millimeter-wave science and technology, subharmonically pumped mixers has received more and more attention. In this study, a balanced sub-harmonic fixtuned mixer is designed based on combination of linear/nonlinear circuit simulation. It is realized based on rogers substrate process to minimize the cost and simplify the assembly. The mixer works in the 91-98 GHz band with SSB conversion loss 8~11 dB when pumped with 6 mW of local oscillator power and minimum SSB conversion loss of 8 dB is measured at 93 GHz. The measured performance of this mixer is sufficient and robust for the foreseen applications.
