    1.Elastic contact is used at the contact point between the connector and the sleeve electrode;
    2.The inner hole of the radiator should match the diameter of the sleeve, and the tolerance should not be too large;
    Operation steps:
    A. Tighten one end of the connector with a thread to one end of the radiator;
    B. Place the sleeve type attenuation plate into the internal hole of the radiator;
    C. Then tighten the connector on the other end with a thread
    D. Attention: Thread requires the use of thread sealant

    Notes

    ■ The sleeve and radiator need to be tightly connected to ensure heat dissipation.
    ■ Good grounding is required to ensure S parameters.
    ■ In order to meet the requirements of the drawings,it is necessary to install radiators of sufficient size.
    ■ If necessary, increase air cooling or water cooling.
    ■ The connection between the connector and the sleeve type attenuation electrode must use elastic contact.
    ■ If the sleeve is marked with "IN", be sure to place one end of the IN on the input port, and if there is no label, it will be bidirectional.
    ◆Remarks:
    ■ We can provide customized RF attenuators, RF resistors, coaxial dummy(termination) loads, and mismatched dummy(termination) loads.
