60 GHz flip-chip assembled MIC design considering chip-substrate effect

In this paper, a 60 GHz MICs with flip-chip assembled pseudomorphic-HEMT is demonstrated. With electromagnetic field analysis, the assembly effect was estimated. An amplifier has a gain of 13 dB and a 30/60 GHz frequency doubler has a gain of -3 dB. Measured and simulated results clarify the potential of the structure and design method.
