The Output Power Characteristics of the Series-connected RTD Pair

Abstract

In this work, the output power of the RTD-pair configuration with two different RTD epitaxial layer structures has been characterized and compared by measurements and simulations. The RTD-pair configurations with the two device structures show the improvement of the maximum output power by a factor of more than 2.5. From the comparison, the RTD with a wider peak-to-valley voltage difference is more beneficial for the enhanced RF power of RTD-pair configuration.
