Abstract

The discrete symmetric heterostructure barrier varactor (HBV) was previously developed as an unbiased frequency-tripling device that needed no second-harmonic idler circuit. Other work investigated nonlinear transmission lines (NLTLs) using discrete varactors attached to linear guiding structures. Fully-distributed Schottky-varactor NLTLs were excessively lossy. This paper explores NLTLs based on fully distributed HBV structures. Using both a modified FDTD method and numerical integration, it is shown that such NLTLs can provide efficient tripling over a wider range of input bandwidth than is possible with fixed-tuned triplers.
