For a parallel RC circuit as shown in figure, R = 20 Ω & C = 0.9 pF, which is to be matched to 50 Ω over a bandwidth,\(\int^{\infty}_0 \ln \frac {1}{|Γ|} dw \le \frac {\pi}{R\; C}\)The circuit has to be matched over 6 GHz to 18 GHz. What is the very best Γ that can be achieved:

• A. 0
• B. 0.05
• C. 0.1
• D. 1
