Behavioral Modeling of Nonlinear RF and Microwave Devices

An explanation of behavioural modelling of nonlinear RF and microwave devices, and a presentation of a powerful curve fitting technique that can be used to describe the behaviour and range of microwave components as a function of multiple independent variables. It features easily-understood mathematical formulae. Using the author’s behavioural modelling methodology, you should be able to generate equations that provide accurate and acceptable reproductions of nonlinear RF and microwave device performance under various conditions. Specifically, you should be able to obtain more accurate representations of saturation and cut-off behaviour; develop more accurate transistor models to generate improved harmonic power output data as a function of power input ranging from small signal to heavy compression, and bias levels ranging from pinch off to maximum allowable current; gain a unified approach to amplifier and transistor characterization of compression characteristic, 1 dB compression point, saturated power output and 3rd order intercept point; and create trade spaces for optimization of sub-system design. The book covers how behavioural modelling is used for bipolar and MESFET device. The accompanying software contains formulae from the text. System requirements: PC-compatible Windows 95/98 with Excel 7.0 or higher; a 486 processor or higher; 16 MB RAM and 1.5 MB hard disk space.
