Microwave multi‐level band‐pass filter using discrete‐time Yule‐Walker method

The modified Yule-Walker scheme is employed to define arbitrary transmission scattering parameter of a multiple-level band-pass filter in the discrete-time domain. Equal-length microstrips including single- and double-section stubs are used to implement the multiple-level band-pass filter. Experimental results are presented to illustrate the validity of this design method. © 2008 Wiley Periodicals, Inc.
