Ku Band Semiconductor T-R Device Production Engineering Measures Program

摘要

The report covers the fabrication and evaluation of the first set of eight engineering model limiters. As PIN diodes were not available for the first stage, all-varactor limiters were made. Four units were constructed with no reverse bias provision, the remaining four incorporated a biasing provision which can be used by the systems designer to obtain considerably lower insertion loss. A major portion of the report is devoted to the development effort leading to the optimized biasing network. A new method to evaluate the power handling capability of varactors through monitoring of the recovery time is also presented. The yield from the fabrication of varactors for the engineering samples is discussed. (Author)
