High Performing RF Solutions For Automotive Antenna Applications

Amphenol RF is pleased to expand its SMA connector portfolio with additional configurations designed for automotive applications. The SMA interface is compact and lightweight and features a secure threaded coupling mechanism that makes it ideal for vibration resistance. These new configurations are designed to support the flexible RTK-044 cable which compliments the low-loss capabilities of the connector. SMA connectors optimized for RTK-044 are well-suited for applications such as infotainment, GPS and satellite radio.

These SMA connectors are available in two configurations: rear-mounted bulkhead jack and right-angle plug. They offer low VSWR and are an excellent solution for applications that require low return and insertion loss like automotive antennas. The jack is engineered with gold-plated, brass bodies and gold-plated, beryllium copper contacts while the plug is manufactured from nickel-plated, brass bodies with gold-plated, brass contact and a stainless steel retaining ring.

Automotive antennas support Wi-Fi, 4G/5G cellular connectivity, Bluetooth, remote start and control, AM/FM/XM and satellite radio, and DSCR/V2X communication sharing protocols between vehicles and external objects to facilitate safety systems, autonomous navigation and intelligent transportation systems.
