Abstract :
Novel micromachined waveguides incorporating Heterojunction Barrier Varactors (HBVs) for millimeter-wave applications have been fabricated. Using measured results an accurate Non-Linear Transmission Line (NLTL) model has been developed and utilised to predict the performance of a NLTL frequency tripler using these waveguides and devices for G-band operation. A port-to-port conversion efficiency for the 3rd harmonic of better than 1.5% over a broad frequency range of 284 to 300 GHz for a fundamental power of 20 mW has been predicted
