SMA (f) connector for RG178 cable

These are high-frequency connectors with screw connection mechanism. The characteristic impedance of the connector is 50 Ohm and the operating frequency range up to 18 GHz. There are two types of SMA connectors, namely SMA and RP-SMA. The connection and disconnection of the connectors is guaranteed for up to 500 cycles. Temperature range is -65 °C to +165 °C. Most of the current cellular routers are equipped with SMA connectors for connecting Wi-Fi / 2G / 3G / LTE / GPS antennas terminated by proticates. It is also used as a standard connector in RF measuring technology. They are characterized by high reliability, durability, high mechanical stability and optimal electrical properties.

This connector is designed for RG178 coaxial cable. The SMA connector includes an O-ring that enhances water and dust sealing properties.
