  • Patent number: 11605924
    Abstract: A radio frequency connector for establishing a radio frequency connection with a radio frequency device is described. The radio frequency connector includes a radio frequency connection interface, an interchangeable radio frequency adapter and a positioning member. The interchangeable radio frequency adapter is detachably attached with the radio frequency connection interface such that the interchangeable radio frequency adapter is configured to be detached from the radio frequency connection interface in a disassembled state of the radio frequency connector. The positioning member is configured to position the interchangeable radio frequency adapter with respect to the radio frequency connection interface in an assembled state of the radio frequency connector.

  • Patent number: 11187723
    Abstract: A high bandwidth differential test probe for measuring a device under test is provided. The test probe comprises a first probe tip arranged at a first coaxial connector relative to a first rotational axis, and a second probe tip arranged at a second coaxial connector relative to a second rotational axis. For adjusting the distance between the first probe tip and the second probe tip, the first coaxial connector is rotatable with respect to the first rotational axis and the second coaxial connector is rotatable with respect to the second rotational axis. Additionally, a tilt angle between the first probe tip and a plane comprising both the first and second rotational axes, and a tilt angle between the second probe tip and the plane, is not equal to zero.

  • Patent number: 10886675
    Abstract: A measurement equipment configured to be connected to a measurement device and an HF coaxial connection element and a torque limiter. The torque limiter is configured for connecting the HF coaxial connection element with the measurement device with a predetermined torque. Furthermore, the invention provides an HF coaxial connection element configured to be connected to a corresponding HF coaxial connection element. The HF coaxial connection element comprises a torque limiter configured for detachably connecting the HF coaxial connection element with the corresponding HF coaxial connection element with a predetermined torque, a centering element for centering the HF coaxial connection element with respect to the corresponding HF coaxial connection element and a twist protection element for preventing twisting motion between the HF coaxial connection element and the corresponding HF coaxial connection element. A corresponding torque limiter is also provided.
