What is SMA in antenna?

SMA (SubMiniature version A) connectors are semi-precision coaxial RF connectors developed in the 1960s as a minimal connector interface for coaxial cable with a screw-type coupling mechanism.

What does SMA cable stand for?

SubMiniature Version A Connector
What Does SubMiniature Version A Connector (SMA Connector) Mean? An SubMiniature version A (SMA) connector is a coaxial cable connector developed in the 1960s as a semi-precision minimal connector interface with a screw-type coupling mechanism for coaxial cables.

Are there different types of SMA connectors?

SMA Connectors have a number of different mounting configurations. The key mounting configurations include: Panel Mount (2-Hole and 4 Hold Flange) SMA Connectors, PCB Mount SMA Connectors, Edge Mount, Bulkhead Mount SMA Connectors, SMT SMA Connectors and Through Hole Mount.

What is reverse SMA antenna?

RP-SMA stands for “reverse polarity” (sometimes also referred to as reverse SMA or for short “R-SMA”). It is designed to prevent the unauthorized connection of an external antenna to increase the range. In an RP-SMA connector, the gender has been changed.

What is the difference between RP-SMA and SMA?

These are coaxial RF connectors developed in the 1960s. RP-SMA stands for Reverse Polarity SMA). It is a variation of the SMA connector which reverses the gender of the interface….Differences of RP-SMA and SMA Antenna Connectors.

SMA Female SMA Male
RP-SMA Female RP-SMA Male

Are SMA and 3.5 mm same?

SMA type will have a foam bead, while 3.5mm uses an air interface. Due to cost, the 3.5mm connector is most often used in metrology applications, whereas the SMA connector is used for production. Because of this, it is not uncommon to see wear and tear degrade the SMA to the point of damaging mated connectors.
