Abstract :
The drift-zone length and optimum doping density of 140 GHz Impatt diodes is evaluated from measurements of the breakdown voltage versus doping concentration. Pulsed and cw n-type single drift diodes were fabricated and the rf-performance was investigated. Relatively high output power levels of 1.6 W (pulsed) and 70 mW (cw) with efficiency values of 2.6 % and 3.2%, respectively, indicate a proper design. Improved repro ducibility can be achieved using a technology with beam-lead diodes and quartz ring packages.
