A study was performed that examines the feasibility of developing an electronically adjustable attenuator for W-band instrumentation applications. All common transmission line structures are considered. An analysis of the merits of each transmission line structure is presented. A fin line structure is presented as having the greatest probability for success. PIN diodes are presented as the most frequency used device for attenuation and control applications. An analysis of the structural, electromagnetic and circuit characteristics was performed. The analysis presented indicates that forward biased, shunt mounted PIN diodes in a fin line structure is a viable approach for continuing investigation for the specified instrumentation application. The conclusions are supported by earlier works that are reviewed in this report.
