“…None of the simulators in [2] [indicated as Monte Carlo coupled with harmonic-balance (MCHB), drift-diffusion with fielddependent mobility (DDHB-fdm), and drift-diffusion with averaged constant mobility (DDHB-am) in Fig. 1] is able to predict the correct power slope and the MCHB code [2] performs worst. Results from our model agree well with measurements for input powers above dBm and reproduce the measured slope.…”

“…The highest conversion efficiency of frequency multipliers is obtained in the transition region between low-and high-power regime and can be only obtained for inductive loads at higher harmonics. The discussion presented below is based on experimental and calculated results for different varactor diodes and different multiplier circuits published in [2], [3], and [8] together with original calculations utilizing our model presented here.…”

“…The modeling and design of Schottky varactor frequency multipliers have received considerable attention due to the progress in device and circuit performance. The key points in this progress have been the enhanced physical understanding of Schottky diode varactor operation [1] and the improvement in analysis methods [2], [3], Schottky diode models [3]- [5], as well as numerical physical device models [2], [6], [7]. In the present work we focus on frequency multiplier analysis based on coupling the circuit-oriented harmonicbalance analysis with drift-diffusion numerical semiconductor device simulation.…”

Design and optimization of frequency multipliers for millimeter and submillimeter wavelengths have been previously performed using harmonic-balance techniques together with equivalent circuit models. Using this approach it is difficult to simultaneously design and optimize the diode device and the multiplier circuit. This work demonstrates results from numerical semiconductor simulation coupled with the harmonic-balance technique. The good agreement between the calculated and published experimental data for the output power and efficiency is essentially due to the incorporation of impact ionization in the numerical model. Details on the device behavior and circuit operation at different power levels are provided.
