We report on a compact high-power 510–560 GHz GaAs Schottky diode based frequency tripler with enhanced power handling capabilities, showing a world-record measured peak power of 30 mW, at room-temperature, when pumped with 350–400 m W. This corresponds to a ten times better performance than previously reported sources in this frequency range. The increase in power handling capabilities is achieved by using an improved epitaxial structure together with an on -chip power combined topology that allows to combine several multiplying structures onto a single chip. The chip also exhibits a state-of-the-art conversion efficiency of 8-9% without any correction for the losses in fixtures/transitions used for the tests.
