WebAccurate modelling of the microwave large-signal characteristics of AlGaAs/GaAs Heterojunction Bipolar Transistors (HBT's) is extremely useful for microwave power applications of the device. This paper presents a new type of HBT large-signal model which is valid for dc, small-signal and large-signal ac modes of operation. The model may be … WebAug 25, 2024 · The problem of self-heating arises due to the increment of lattice heat temperature that reduces mobility and hence output current reduces. This problem not only affects the performance of the device but degrade it also. To reduce the self-heating effect, employment of Silicon substrates 22 22. I.
