Abstract
High frequency operation of an integrated circuit test system is greatly extended by incorporation of dielectric bushings in a contactor assembly to maintain the coaxial transmission line characteristics over a larger frequency range. The provision of a balanced line structure allows for higher impedance characteristics over a broader frequency range and mitigates grounding problems. Elevated grounding annuli are incorporated to improve signal isolation and reduce the effect of undesired waveguide modes.
