摘要：

Load impedance variations were obtained using an innovative integrated tuner at G-band. The 200 GHz load-pull measurements on a silicon-germanium (SiGe) heterojunction bipolar transistor (HBT) are presented. First, the linearity of the integrated tuner is checked. Then, the main load-pull characteristics are extracted from a 0.13 x 3 mu m(2) emitter area SiGe HBT. The aim of this study is to provide a solution to avoid losses related to probes and commercial tuners. Thereby, from design to measurements, power setup architecture, calibration and performances at 200 GHz are performed in a non-50 Omega environment. Finally, comparisons between measurements and simulation from a high current model (HICUM) show good agreement, demonstrating the capability of the measurement approach.
