  • Implementing handheld transfer impedance probe
    Patent number: 9417266
    Abstract: A method and structures implement an enhanced handheld transfer impedance probe including a rigid probe housing body that carries a pair of coaxial RF connectors providing connections to a network analyzer. A base member includes a respective pair of independent electrical contacts and a common interconnect electrical contact. Each of the respective electrical contacts includes a respective associated electrically conductive compressible pad. Each respective compressible pad extends between rigid stops having a set height to limit gasket compression and enable repeatable gasket compressions for repeatable measurements with the handheld transfer impedance probe. An interconnection structure includes respective interconnects connecting between the coaxial RF connectors and respective electrical contacts.
