This paper presents an empirical table-based nonlinear HEMT model fully extracted from time-domain large-signal measurements. A simple and direct extraction procedure, based on a vector nonlinear network analyzer measurement system with load-pull fac

This letter presents an optimized single-stage MMIC tripler with W-band output frequency (76.5 GHz). The circuit is based on an 0.15 /spl mu/m gate-length AlGaAs/InGaAs/GaAs PHEMT. By using a class AB transistor bias point and carefully selecting its

The authors present a simple and accurate procedure for the direct extraction of the quasi-static FET model nonlinear charge functions from large signal measurements. The method is based on the proper use of a vector nonlinear network analyzer (VNNA)

For 76-GHz transmitters, two coplanar monolithic microwave integrated circuit (MMIC) frequency multipliers were realized in a 0.15-/spl mu/m pHEMT technology on GaAs. A 38/76-GHz frequency doubler achieved a state-of-the-art output power of 10 dBm fo

Full two-port large signal on-wafer waveform measurement systems, based on the HP Microwave Transition Analyzer (MTA), have recently been developed. These systems can allow for both small-signal S-parameters measurements in the frequency domain and l

In this paper, a novel theoretical comparison of MESFET and HEMT performances as frequency multipliers for different harmonic orders is presented. Additionally, three W-band single-ended coplanar PHEMT MMIC multipliers (a doubler, a tripler and a qua

In this paper, a simplified nonquasi-static table-based approach is developed for high-frequency broad-band large-signal field-effect-transistor modeling. As well as low-frequency dispersion, the quadratic frequency dependency of the /spl gamma/-para

We will present here a technique which allows for the accurate real time extraction of the intrinsic current state functions of a quasi-static HEMT model from time domain large signal waveforms. This is achieved by presenting an appropriate load impe
