Abstract. This paper presents the application of vector fitting method to the
estimation of pole-model parameters proposed for transfer function of multiport
wideband microwave devices. The example of system identification made for
simulated data of microstrip two-port filter is demonstrated; the verification
step shows the model consisting of eight poles approximates the frequency
response of the device with very high accuracy.
