1. Process of calculation to make Lowpass filter using Richard transformation, Kuroda identities

(1) Spec of design
Object: Fabricate Lowpass filter using stubs
Cut-off frequency: 2GHz
Order N: 3
Impedance: 50ohm
Characteristic: 0.5dB equal ripple

(2) Answer
Step 1. Find g1,g2,g3,g4

→ First, we find g1,g2,g3,g4 when N is 3 and it has 0.5dB equal ripple. So these values are g1=1.5963, g2=1.0967, g3=1.5963, g4=1

3. Lowpass filter fabrication using Ideal line(TLIN,TLOC) in ADS
(1) Circuit and graph
CKT of Lowpass filter using Ideal line(TLIN,TLOC) in ADS
S-Parameter graph of LPF using Ideal line
Zoom in scale of S-21

(2) Spec of design
Object: Fabricate Lowpass filter using Ideal line
Cut-off frequency: 2GHz
Order N: 3
Impedance: 50ohm
Characteristic: 0.5dB equal ripple

(3) Answer
→ We use Ideal line(TLIN,TLOC) in ADS by designing like above circuit. the results are came out like above graph. Since we use ideal line, input signal that is red line above graph is rippled sharply. And see the zoom in scale output value in graph, we can check that the output signal is rippled in 5dB scale.
