This project developed the technology required to develop electro-thermal behavioral models of microwave circuits and subsystems. Electrical behavioral models themselves are poorly developed however we have developed an electrical behavioral model that can be readily extracted from single tone measurements or simulations and capture baseband effects and in particular thermal effects. The core technology is based on mathematics developed by the authors called the Arithmetic Operator Method which enables the basic mathematical operations such as addition, multiply, divide and subtraction of signals to be performed by operating on their spectra. An example of application of the method to the modeling of a logarithmic amplifier are presented. The model was implemented in MATLAB code and this code is available by contacting m.b.steerieee.org. The code has been transferred to two MURIs Multidsciplinary University Research Initiatives managed by the Army Research Office. In the first MURI the work developed here will be used to model quasi-optical power combining amplifiers. In the second MURI the work will be used to model the co-site interference problem.
