چکیده
This paper describes the performance of pianar back-to-back Barrier-N-N+ (bbBNN) devices for mmand submm wave multiplier applications. A technique has been deveioped for characterizing pianar bbBNN devices with Vector Network Anaiyzer, which gives both the series resistance and voitage dependent capacitance of the device. Resuits show that bbBNN devices do not have a high series resistance iike BarrierIntrinsic-N+ (BIN) devices. Multiplication efficiency of bbBNN devices has been calculated using iarge signai anaiysis approach. A high Cmax/Cmin ratio is essentiai for high efficiency. The embedding impedance requirement has aiso been anaiyzed. So far, fiange-to-fiage tripiing efficiency of 2.9°/0 has been achieved using these pianar devices in a 200 GHz crossed waveguide mount. l-he efficiency at the device is estimated to be about 6°/0. .

متن کاملA New Scheme for the Design of Balanced Frequency Tripler with Schottky Diodes
We propose a balanced frequency tripler scheme for millimeter-wave and submillimeter-wave application, in which doublesided suspended stripline is adopted. Two arms of Schottky diodes are mounted on the upper side of the substrate, and the other two arms of diodes are mounted on the lower side. The diodes are DC biased without bypass chip capacitor, which is essential in the common used balance...
