RP-SMA Right Angle Cables & Adapters
Antenna Cables with RP-SMA Right-Angle Connectors
Design and Structure:
- RP-SMA: "RP" stands for "Reverse Polarity," and "SMA" stands for "SubMiniature version A." The RP-SMA connector is similar to the standard SMA connector but has the gender of the interface reversed. In an RP-SMA setup, the male connector has a center socket instead of a center pin, and the female connector has a center pin instead of a center socket.
- Right Angle: The term "right angle" refers to the angle at which the connector is built in relation to the cable. A right angle connector is designed at a 90-degree angle, which can be particularly useful in tight spaces or where a straight connector could be prone to damage or cause inconvenience.
- Antenna cables with RP-SMA right angle connectors are widely used in wireless communications, including Wi-Fi routers, antennas, RF coaxial cables, and other devices where space is limited or where a straight connector would protrude awkwardly. The right-angle design helps in managing space efficiently and reducing stress on the cable.
- RP-SMA connectors are often used in Wi-Fi equipment, but due to their reverse polarity design, they are not directly compatible with standard SMA connectors. This design difference is intentional to prevent mismatching in sensitive RF applications.
- The right-angle design can sometimes introduce a very slight increase in signal loss compared to straight connectors, but in many practical applications, this loss is negligible. The choice of a right-angle connector usually depends more on the physical requirements of the installation rather than performance considerations.
Installation and Use:
- When installing or using RP-SMA right angle connectors, it's essential to ensure that they are fully and correctly screwed on to achieve optimal connection and performance. Also, it's crucial to match these connectors with the appropriate cable type and impedance (usually 50 ohms) for your specific application.
- The main advantages of using an RP-SMA right angle connector are its compact design, which is beneficial in tight spaces, and its ability to reduce the risk of damage to the cable or equipment due to bending or pressure.
Data Alliance produces our shorter RPSMA right-angle cables with LMR-100-equivalent, doubled-shielded low-loss coaxial cable, and the longer lengths we produce with LMR-200 equivalent coax.
