This paper explains and summarizes a new attempt to derive a general mathematical model
[GMM] to simulate surface acoustic wave (SAW) filters, using the superposition principle and delta function
model. GMM can be used to simulate One-to-One, One-to-Multi and Multi-to-Multi SAW filter devices. The
simulation program was written using MATLAB (the language of technical computing). Four-design structures
(One-to-One, One-to-Two, One-to-Three and Ten-to-Ten) ware selected to test the correctness of GMM. The
frequency response of the simulation and test results are similar in center frequency and 3-dB bandwidth, but
the insertion loss is different, because of some second order effects (Issa Haitham, 1999).
