Patent ID: 7042232

Claim:
A distributed resistor for use in a probe system, said probe system operating over a range of frequencies, said distributed resistor comprising: (a) a substrate, said substrate having a substrate frontside and oppositely positioned substrate backside, said substrate having a substrate first end and oppositely positioned substrate second end; (b) a first termination at said substrate first end and a second termination at said substrate second end; (c) a frontside resistor on said substrate frontside, said frontside resistor having a first frontside resistor end and a second frontside resistor end, said first frontside resistor end connected to said first termination and said second frontside resistor end connected to said second termination; (d) a backside resistor on said substrate backside, said backside resistor having a first backside resistor end and a second backside resistor end, said first backside resistor end connected to said first termination and said second backside resistor end free from said second termination; (e) said frontside resistor and said backside resistor capacitively coupled through said substrate; and (f) said distributed resistor having an attenuation that decreases proportionally to the square root of frequency over said range of frequencies.
