Abstract :
We report on a state-of-the-art monolithically integrated heterostructure barrier varactor (HBV) frequency tripler operating in the W-band frequency range. The device utilizes series connection of four HBV diode mesas, with total 12 barriers, and a cross section area of 700 μm2. The presented tripler withstands 800 mW input power, while delivering 185 mW of output power at 107 GHz. The corresponding conversion efficiency was measured to be 23% and the circuit exhibited 15% 3-dB bandwidth.
