A W-band balun integrated probe with common mode matching network

There has been a growing interest in developing differential Millimeter-wave Monolithic Integrated Circuits (MMICs) in recent years. The characterization infrastructure for these differential devices however, is still limited at higher frequencies. In this paper, a balun integrated probe is designed to cover the entire W-band (75 - 110 GHz) with the potential to be scaled to even higher frequencies. Test structures of the balun are characterized...
