Product Description
Reverse Polarity SMA (RP-SMA) connectors are precision RF connectors designed for secure and reliable signal transmission in high-frequency applications. Featuring a threaded coupling mechanism and reverse polarity interface, these connectors ensure compatibility with specific RF systems while preventing mismatched connections. Commonly used in Wi-Fi antennas, wireless communication devices, and RF modules, RP-SMA connectors offer excellent electrical performance, durability, and consistent impedance (typically 50 ohms) across a wide frequency range.

FAQs
What is an SMA connector?
SMA (SubMiniature version A) is a precision RF coaxial connector designed for high-frequency signal transmission. It is widely used in RF, microwave, and test & measurement applications up to 18 GHz (and higher for precision versions).
What cable types are compatible with SMA connectors?
SMA connectors are compatible with commonly used RF coaxial cables such as RG174, RG178, RG316, RG58, RG402, RG405, and low-loss RF cables depending on application needs.
Do you provide custom SMA cable assemblies?
Yes, custom SMA cable assemblies can be manufactured based on cable type, length, connector orientation, frequency range, and environmental requirements.
How do I choose the right SMA connector for my application?
Choosing the right SMA connector depends on operating frequency, cable type, mounting style, power handling, and environmental conditions.
What materials are used in SMA connectors?
SMA connectors are typically manufactured using brass or stainless steel bodies, gold or nickel plating, and PTFE dielectric for stable RF performance.
