Hi,
Could anyone tell me what if I have resonance at one frequency when I cascade two microstrip bandpass filter? All other frequencies are Okay except one point(see attachment).
Obviously I can remove it by using an ideal isolator in-between the two filters. Is there any simple but feasible way to remove it? I tried to use the single stub but seemed useless.
