A K-Band Frequency Tripler Using Transformer-Based Self-Mixing Topology With Peaking Inductor

This article presents a K-band frequency tripler with bandwidth enhancement techniques. A transformer-based self-mixing topology with peaking inductor (TSM-PI) is introduced to settle the drawbacks in DC distortion, bandwidth, and output voltage of the conventional self-mixing structure. Theoretical analyses compared with the conventional one are proposed, which shows the TSM-PI structure improves...
