A Back-To-Back Barrier-N-N+ (bbBNN)Diode Tripler at 200 GHz
This paper describes the performance of planar back-to-back Barrier-N-N+ (bbBNN) devices for mm and submm wave multiplier applications. A technique has been developed for characterizing planar bbBNN devices with Vector Network Analyzer, which gives both the series resistance and voltage dependent capacitance of the device.

Planar diode multiplier chains for THz spectroscopy
High-resolution laboratory spectroscopy is utilized as a diagnostic tool to determine noise and harmonic content of balanced [9]-[11] and unbalanced [12]-[14] multiplier designs. Balanced multiplier designs suppress unintended harmonics more than -20dB. Much smaller values were measured on unbalanced multipliers.
