A distributed heterostructure barrier varactor frequency tripler [PDF]
IEEE Microwave and Guided Wave Letters, 2000 We present a broadband nonlinear transmission line (NLTL) frequency multiplier at F-band. The multiplier consists of a finline section periodically loaded with 15 heterostructure barrier varactor (HBV) diodes. Tapered slot antennas are used to couple the fundamental signal from a WR-22 rectangular waveguide to the distributed multiplier as well as ...
