Double barrier resonant tunneling diodes in frequency multiplier applications performances study

Abstract

This paper presents a computer aided study of the performances that can be obtained by using the Double Barrier Tunneling (DBRT) diodes in frequency multiplier applications. The Harmonic-Balance method is used to analyse the circuits. It is shown that the conversion efficiency and also the output power versus input power have a hysteresis type behaviour. The multiplication efficiency which results from the simulations is compared to the theoretic and previously reported ones. It is shown that the negative differential resistance region does not lead to conversion losses diminishing.
