Problem:<br />
Unwanted and unmanageable <strong>in</strong>ductive or capacitance<br />
parasitics<br />
Solution:<br />
• Parasitic <strong>in</strong>ductance<br />
and capacitance are<br />
reduced by<br />
controll<strong>in</strong>g<br />
impedance to be<br />
closer to 50Ω<br />
• Parasitics are further<br />
reduced by<br />
m<strong>in</strong>imiz<strong>in</strong>g height of<br />
the contactor<br />
• If <strong>in</strong>creased<br />
impedance is<br />
required, adjacent<br />
ground contacts can<br />
be removed<br />
