Expanded reverse polarity SMA portfolio with additional cable mount connectors

Amphenol RF has expanded its SMA connector series with further reverse polarity (RP) configurations. RP-SMA’s are a variation of the conventional SMA interface which reverses the gender of the connector’s contact pin with no effect to the electrical or mechanical performance. The new RP-SMA options comprise plug and jack versions which are compact, lightweight connectors that offer a robust design for usage with various ultraminiature micro-coax cable types. These connectors are created with a secure threaded coupling mechanism, making them excellent for vibration resistance applications with specific space constraints.

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

They are created specifically to be terminated to micro-coax cable types such as 0.81mm, 1.32mm and 1.37mm, which enable a high degree of flexibility. This interface is incredibly versatile, making them ideal for various wireless applications, including WLAN, cellular devices and Wi-Fi.

The reverse polarity SMA interface also delivers 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 only the antenna or cable would require to be replaced, which has extra time-saving advantages.
