What are RP-SMA Coaxial Adapters?
RP-SMA stands for Reverse Polarity SubMiniature Version A. It is an RF connector interface that uses reverse-polarity center-contact geometry compared with a conventional SMA connector of the corresponding gender designation.
RP-SMA Coaxial Adapters allow compatible RF interfaces to be connected without replacing the existing cable, antenna, or equipment connector. They are commonly used in wireless networking, Wi-Fi antennas, RF communication devices, and other systems requiring compatible reverse-polarity connections.
When selecting an adapter, it is important to verify the connector gender, center-contact configuration, impedance, frequency range, and mating compatibility.

Frequently Asked Questions
An RP-SMA Coaxial Adapter is an RF connector component designed to connect compatible reverse-polarity SMA interfaces or adapt an RP-SMA interface to another compatible connector type.
The primary difference is the center-contact configuration. RP-SMA reverses the center pin and socket arrangement relative to the corresponding conventional SMA connector genders. Always verify the connector geometry before mating.
Many RP-SMA adapters are designed for 50 Ohm RF systems, which are common in wireless networking and communication equipment.
The frequency range depends on the adapter design and connector configuration. Selected models may support up to 18 GHz, but the exact rating should be verified from the product datasheet.
They are commonly used in Wi-Fi routers, access points, wireless antennas, RF modules, wireless communication equipment, and testing systems.
Not universally. Although some configurations can physically mate, connector gender and center-contact geometry must be checked to ensure compatibility and avoid damage.
Right-angle configurations are available in the market and can be specified where the selected product range supports them. Confirm availability for your required model.
Connector combinations, mounting styles, materials, and other specifications can be discussed according to the required application and manufacturing feasibility.
Check the connector type at both ends, center-contact configuration, impedance, operating frequency, mounting style, and the required electrical specifications.
