Abstract
In this paper, we demonstrate the monolithic integration of two resonant tunneling diodes (RTD) to make a THz mixer circuit. The circuit uses two RTDs, which are integrated in one carrier substrate. The RTDs are biased independently. The fist RTD operates as an oscillator and provides the local oscillator signal for the second RTD operating as a mixer. The measurements demonstrate that a monolithic integration of several RTDs in one substrate is feasible. This offers new possibilities for RTD based wireless communication and sensing systems.
