Master Thesis: Investigation of a 35-nm metamorphic HEMT distributed frequency multiplier MMIC

Background

Fraunhofer IAF is one of the world‘s leading research institutions in the field of III-V semiconductors and synthetic diamond developing technologies for use in communication, energy, mobility, industry and medicine.

Scientific goals:

• Investigation and demonstration of the feasibility of a distributed frequency multiplier for implementation in a future broadband mm-wave signal source.
• The MMIC should achieve a wideband frequency multiplication with sufficient output power to drive the next component within its chain (e.g. next frequency multiplier or up-/down-converter mixer).
• The targeted frequency and bandwidth will be assessed during the first steps of the work after decision on the MMIC architecture and first simulations.

• The MMIC will be fabricated using one of IAF’s mHEMT process. In order to achieve a high level of miniaturization, a design based on thin-film microstrip line (TFMSL) is currently envisioned.

Tasks

• Review the theory, design and analysis of frequency multipliers and literature research.
• Circuit design simulation and layouts.
• Documentation.
