RP-SMA Adapters, Couplers, Joiners, Gender-Changers

Our RP-SMA adapters are precision machined and gold or nickel-plated for resistance to the elements and low loss.

RP-SMA female connector is also called "RP-SMA jack" and RP-SMA-male is also called "RP-SMA plug."

Our antenna cable adapters are compatible and compliant for all types of wireless applications, including:

  1. WiFi (WLAN): Suitable for WiFi and WiMax networks:  Wi-Fi 6, WiFi 6E, 802.11AX, 802.11N, AC, G, A, B. 900MHz, 2.4GHz & 5GHz applications. The most typical application of RP-SMA connectors is in WiFi technology.  Devices (operating on IEEE 802.11 standards (such as 802.11b/g/n/ac/ax) often have RP-SMA connectors (not SMA) for external antennas.

  2. Cellular:  LTE (4G), GSM (3G): While less common than in Wi-Fi devices, some cellular equipment, especially boosters or certain types of antennas, might utilize RP-SMA connectors

  3. BlueTooth: Some devices, especially those designed for extended range or industrial applications, may utilize external antennas with RP-SMA connectors.

  4. IoT wireless protocols:  LoRa , NB-IoT, ZigBee, LTE-m, RFID:   The Internet of Things (IoT) devices, especially those that need to cover larger areas, might use antennas with RP-SMA connectors. Zigbee, for instance, is a low-power, high-range protocol often found in home automation: 

RP-SMA = Reverse Polarity SMA. RP-SMA is a round screw-type connector, with medium-sized, threaded coupling connectors.

  • The length of our standard RP-SMA-female connectors (threaded part) on adapters is 3/8 inches.

Diameters of RP-SMA male and female connectors:

  • RP-SMA female outside diameter is 5/16" (7.9375mm): Accommodates a hex nut (bulkhead nut) with 5/16" nominal outer diameter
  • RP-SMA male inside diameter is 5/16" (7.9375mm)(the inside diameter where the threads are).
  • RP-SMA-female requires a 6.5mm hole.

RP-SMA Adapter Composition:

Lead-free and ROHS compliant: All of our RF adapters and antenna cables are ROHS compliant.

Impedance-matched to 50 ohm antennas and cables.

Adapters with RP-SMA Connectors: Applications

The world of wireless technology is vast, and as it continues to evolve, the devices that drive this evolution are underpinned by an intricate network of components. One such component, often overlooked but vital, is the adapter with an RP-SMA connector. This article delves into the applications and the wireless technologies that make use of adapters with one or more RP-SMA connectors.

Applications of Adapters with RP-SMA Connectors

  1. Wireless Routers and Access Points: Many modern wireless routers and access points utilize RP-SMA connectors to attach external antennas. By using an external antenna, the range, and the quality of the wireless signal can be enhanced.

  2. Wi-Fi Antennas: High-gain Wi-Fi antennas often come with RP-SMA connectors, making them compatible with the vast majority of commercial wireless networking gear.

  3. RF Amplifiers and Signal Boosters: RP-SMA connectors are frequently used in RF amplifiers and signal boosters. These devices amplify weak signals to increase coverage and performance.

  4. Wireless Adapters: Some USB or PCI/PCIe wireless adapters for computers have detachable antennas connected via RP-SMA. This allows users to replace the stock antenna with a higher-gain version for better performance.

  5. Ham Radio: Amateur radio enthusiasts, or "hams", sometimes employ adapters with RP-SMA connectors in their setups, especially when dealing with UHF and SHF frequencies.

  6. Instrumentation: Various RF measurement devices, like spectrum analyzers and signal generators, might have RP-SMA connectors.

What is an RP-SMA Connector?

The RP-SMA (Reverse Polarity SubMiniature version A) connector is a type of RF (radio frequency) connector that is commonly used in the realm of wireless networking equipment. Unlike the standard SMA connector, the RP-SMA has its male and female roles reversed. This design was initially introduced to comply with certain regulations, ensuring that home users wouldn't connect antennas with gain (increased power) to their devices, potentially interfering with other equipment or services.

Conclusion

The RP-SMA connector, while small and seemingly insignificant, plays a pivotal role in the realm of wireless technology. Whether it's ensuring that a home Wi-Fi network has optimal coverage or facilitating critical communications in a vast industrial setup, adapters with one or more RP-SMA connectors are at the heart of many wireless innovations. Recognizing the value and application of these connectors gives a deeper appreciation for the intricate web of components that power our increasingly connected world.
