KC908 adopts a RF socket with a inner diameter of 2.92mm, which is
compatible with SMA standard, and the actual cutoff frequency can reach
40GHz. Although the socket has been strictly reinforced, it cannot withstand
massive force due to its structure, inherently.
that the core of the connector is extremely fragile despite the solid shell of the
connector. The main cause for damage is the core has been waggled and this
cannot be seen from outside.
should be followed.
(1) It's not recommended to alter SMA to a larger connector. For instance,
soft connecting cable between SMA connector and N connector is preferred
when N type is desired, instead of SMA/N adapter.
(2) When connecting between SMA sockets or connecting to a smaller
socket, short adapater whose length is shorter than 50mm is preferred. Soft
cables can serve as a replacement if such adapter is not available. Long
adapters will drastically multiply the torque applied on the socket, which
would consequently damage the socket.
(3) Straight adapters are preferred over curved adapters. Since curved
adapters would possibly stretch outside the dimensions of the machine, and
once the machine tilts accidentally, enormous torque would be applied to the
socket and damage it.
(4) Use
50Ω SMA adapters or 2.92mm connector. 3.5mm connectors from
certain providers could possibly damage the core.
