Reduce the complexity of Wi-Fi and antenna devices with new RP-SMA connectors

Amphenol RF expands its reverse polarity SMA line with additional cable mount connectors designed for use with highly flexible micro-coax cable types.

Amphenol (NYSE:APH)

DANBURY, CT, USA, June 10, 2022 / — Amphenol RF is pleased to announce the expansion of its popular SMA connector series with additional Reverse Polarity (RP) configurations. RP-SMAs are a variation of the traditional SMA interface that reverses the gender of the connector’s contact pin without affecting electrical or mechanical performance. New RP-SMA options include plug and jack versions which are compact, lightweight connectors that feature a rugged design for use with various types of ultraminiature micro-coaxial cables. These connectors are designed with a secure threaded coupling mechanism which makes them ideal for vibration resistant applications with certain space constraints.

RP-SMA plugs and sockets 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 mate with micro-coax cable types such as 0.81mm, 1.32mm and 1.37mm, allowing for a high degree of flexibility. This interface is extremely versatile, making them ideal for a variety of wireless applications including WLAN, cellular devices and Wi-Fi.

The reverse-polarity SMA interface also provides an added advantage over traditional SMAs for long-term use. With frequent screwing and unscrewing, the inner conductors often wear out and lead to a decrease in signal strength. Replacing this connection can be a complex process. With an RP-SMA connector, if worn, only the antenna or cable would need to be replaced, which has additional time-saving benefits.
