ABOUT

I am Han-Yu Tsao, an Electrical Engineering Ph.D. candidate at the University of Virginia (UVA) in the United States. I was an RF Engineer at Compal computer manufacturer. My primary research interests are the millimeter wave and sub-millimeter wave device developments and integration. Since I joined the UVa ECE Ph.D. program, I have developed several millimeter devices which include: High-Q factor inductors, reflectionless filters and chip-to-chip detachable interconnects.

My dissertation is a chip-to-chip detachable interconnect between 140 GHz and 220 GHz building on the 15 µm SOI wafer. The chip-to-chip interconnects design contains two significant concerns, electrical performance, and mechanical stress control. First, the impedance match from the E-plane probe to interconnects. Second, the mechanical stress on the interconnects beam. The interconnect's beams have to provide enough stress to hold the connections but not too strong to break the beams.

I have TA'ed for RF Circuit Design & Wireless Systems at UVa. As a teaching assistant, I lead the lab section and assisted students design and measuring the RF circuit boards from the matching network, LNA, VCO to the Mixer. I have strong lab measurements and RF circuit debug experience.
