Power De-rating
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
P/N Designation
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.
