SMA Male/Female Adaptor
All RF connectors wear with use. The RF Explorer SMA ports are subject
to minimal wear each time the connector interface is coupled and de-
coupled with an antenna, a SMA cable, an attenuator or a RF device of
any kind.
If you repeat plug/unplug operations over the RF Explorer SMA port
hundreds of times, the SMA port may underperform over time and exhibit
undesired attenuation.
To protect the SMA port for frequent plug/unplug operations, you can use this adaptor and keep it directly
attached to the RF Explorer port. Then you plug/unplug other RF devices into this adaptor, not the original
SMA port. After hundreds of operations, if the adaptor wear and show attenuation or reliability problems, you
can just replace it by a new one and always keep your original RF Explorer SMA port intact.
SMA Termination – 50 ohm dummy load
Using SMA termination or Dummy Load is suggested for protection of the
SMA port of your RF Explorer when the device is exposed to unwanted
high radiation or strong electronic fields.
For instance, if you carry on your RF Explorer that is exposed to an X-Ray
scanner in the airport, you should remove the SMA antenna and plug a
protection 50 ohm SMA termination.
SMA termination are also required when using Signal Generator while not
connected to an antenna; in this way the generator sees a correct load to avoid damage.
