Abstract :
A novel distributed small-signal HBT model at millimeter-wave frequencies is proposed. This new approach is based on an electromagnetic simulation on the extrinsic passive part of an HBT. The S-parameters of the HBT intrinsic active part are computed by using the "multi-port connection method" (K.C. Gupta et al, Computer-aided design of microwave circuits, Artech House Inc., 1981). Then, values of all the HBT intrinsic model elements can be obtained by using explicit analytical expressions. Good agreement between the measured and the simulated results has been demonstrated.
