Abstract :
We propose a large signal model for a packaged SiGe heterojunction bipolar transistor. Pulsed I-V measurements are used to avoid thermal effects. The current model yields excellent correlation with pulsed output characteristics and S-parameters up to 18 GHz. The model´s validity is established by designing ultra low phase noise C and X band dielectric resonator oscillators (DROs).
