SMA Connectors for Automotive Cables

Amphenol RF offers an expanded line of 50 Ω SMA connectors optimized for traditional low-loss automotive cable types: TFC-302LL, TFC 3.6 mm LL-50, RTK301, RTK-044, and DACAR-302. The SMA interface is compact and lightweight and available in bulkhead jack, straight, and right-angle plug configurations. These connectors are ideal for applications where low return loss and vibration resistance are necessary. The SMA interface supports frequencies up to 18 GHz ensuring optimal performance through 6 GHz, the cut-off frequency of the cable, and utilizes the popular threaded coupling mechanism. All designs feature a cable crimp termination which allows for quick and secure assembly using standard hex crimp tooling and a soldered center contact. Low-loss cable types are designed to offer reliable electrical and mechanical performance. They feature a stranded center and complement the low-loss capabilities of the SMA connector. All supported cables are highly flexible and offer stable impedance and low signal attenuation.
