Amphenol RF announced the expansion of their popular SMA connector series with additional reverse polarity (RP) configurations. RP-SMA’s are a variation of the traditional SMA interface which reverses the gender of the connector’s contact pin without affecting the electrical or mechanical performance. The new RP-SMA options include plug and jack versions which are compact, lightweight connectors that feature a robust design for use with various ultraminiature micro-coax cable types. These connectors are designed with a secure threaded coupling mechanism which makes them ideal for vibration resistance applications with certain space constraints.

RP-SMA plugs and jacks alike provide excellent electrical performance up to 6 GHz and are manufactured with durable gold plated, brass bodies and gold plated, beryllium copper contacts. 

They are designed specifically to be terminated to micro-coax cable types such as 0.81 , 1.32 and 1.37 mm which allow a high degree of flexibility. This interface is extremely versatile which makes them well-suited for a variety of wireless applications including WLAN, cellular devices and Wi-Fi.

The RP SMA interface also offers an additional benefit over traditional SMA’s for long-term use. With frequent screwing and unscrewing, the inner conductors often wear out and cause the signal strength to decrease. It can be a complex process to replace this connection. With an RP-SMA connector, in the event of wear, only the antenna or cable would need to be replaced which has added time-saving advantages.
