A novel and accurate method for the direct extraction of HBT small-signal hybrid-Pi model parameters is proposed. The main feature of this method is that a unique set of intrinsic parameters is calculated for the whole frequency range of operation using a least-squares data fitting algorithm. This algorithm consists of an estimation from measured S-parameters of a set of new analytical equations derived from the intrinsic HBT equivalent-circuit Y-parameters. Experimental validation on an HBT
