Abstract:

Frequency multiplier microwave monolithic integrated circuits MMICs can be used for a variety of radio frequency RF and microwave systems. Several frequency doublers were designed using a 0.13-m gallium arsenide GaAs pseudomorphic high electron mobility transistor PHEMT process from TriQuint Semiconductor. The original design and fabrication of these circuits was performed as part of the fall 2011 Johns Hopkins University JHU MMIC Design Course, taught by the author. As noted in the previous technical note, ARL-TN-0517, Monolithic Microwave Integrated Circuit MMIC Frequency Doublers, the measured results for the open circuit stub to attenuate the fundamental harmonic indicated that an electromagnetic EM simulator, such as Sonnet EM, more accurately modeled the performance compared to a standard microwave linear simulator. The length of the stub attenuators were corrected and refabricated as part of the fall 2012 JHU MMIC Design Course. The measurements of the second pass 8- and 16-GHz frequency doublers with harmonic stubs are documented in this follow up technical note.
