Abstract :
Novel lumped-element coplanar waveguide-to-coplanar stripline transitions are proposed, using the planar lumped-elements to realize the low-pass and high-pass filter responses. Simple equivalent-circuit models are also established, from which the characteristics of various lumped-element transition structures are examined. Specifically, a low-pass lumped-element transition with 3 dB cutoff frequency at 3.2 GHz and a high-pass lumped-element transition with 3 dB cutoff frequency at 1.6 GHz can be achieved.
