Coupled-Line Bandpass Filter

Application ID: 12012

It is possible to realize a narrowband bandpass filter using cascaded microstrip coupled lines. In this example, a design composed of cascaded microstrip lines, each approximately a half wave length in size at the resonant frequency, is analyzed. The model is solved for the S-parameters and a very narrow bandwidth is observed.

This model example illustrates applications of this type that would nominally be built using the following products:
