Probe with absorbing materials

In this paper through integrating absorbing materials onto a probe as terminators to eliminate the reflected noises on device under test (DUT), a novel on-probe termination technique is introduced for high frequency measurements. Absorbing material is suitable for on-probe termination, since there is no need of “ground” which is required in conventional resistive termination, and it also provides better flexibility in on-probe design. Measurement are performed to test the feasibility of proposed technique. Results show absorbing terminators can effectively terminate reflected signals and eliminate noises. The proposed technique provides innovative on-probe termination solution for cost reduction or/and feasibility improvement in high frequency measurements.
