Claims

[Scope of utility model registration request]

In a measurement jig for measuring microwave electrical characteristics between opposing lead pins of an IC package, a pair of network analyzer terminals are connected to the open ends of a flexible coaxial cable and arranged symmetrically. A pair of conductor blocks with a microstrip line connected and fixed at one end to the core wire of the coaxial cable exposed on the top surface and surrounded by shallow walls on three sides, and an IC to be measured with lead pins led out in both directions. A central conductor block on which the package is mounted, shallow wall portions standing up on opposite sides along the lead-out direction of the lead pins and joined and clamped by the pair of conductor blocks, and a wall portion of the pair of conductor blocks. and a dielectric plate that covers the entire surface of the microstrip line and fixes the other end of the microstrip line and the lead pin so that they are in pressure contact with each other, and the relative position of the conductor block husbands is varied so that continuous measurement can be carried out. A jig for measuring a microwave IC package, characterized in that:
