Overview
RP-SMA connectors are a reverse-polarity variant of standard SMA RF connectors, designed to comply with specific regulatory and compatibility requirements in wireless systems. They share the same mechanical interface as SMA but with inverted gender on the center contact.
Available configurations
- RP-SMA male and RP-SMA female
- Straight and right-angle connectors
- Panel-mount, bulkhead and cable-end versions
- Interfaces for common RF coaxial cables
Technical characteristics
- 50 Ω characteristic impedance
- Threaded coupling for vibration resistance
- Typical frequency range up to microwave bands
- Materials and plating suitable for RF signal integrity
Applications
RP-SMA connectors are widely used in Wi-Fi access points, wireless routers, antennas, RF test equipment and IoT devices where reverse polarity is required to avoid incorrect mating.
Frequently Asked Questions
What does RP-SMA mean?
RP-SMA stands for Reverse Polarity SMA. The connector has the same outer thread as SMA but an inverted center pin configuration.
Are RP-SMA and SMA compatible?
No. Although mechanically similar, the center contacts differ and they should not be mated.
Where are RP-SMA connectors commonly used?
Mainly in Wi-Fi, WLAN and wireless communication equipment.
Is RP-SMA male the same as SMA male?
No. RP-SMA male has a female center contact, unlike SMA male.
Which cables are typically used with RP-SMA?
They are available for common 50 Ω RF coaxial cables such as RG series.
Why is reverse polarity used?
It is often adopted to comply with regional regulations and to prevent unauthorized antenna replacement.
