Straight SMA Female Connector, Solder Cable Type, 50 Ohm
Introduction
Engineered for superior performance and reliability, this SMA connector is the ideal solution for creating high-quality RF cable assemblies. It is precision-machined for dependable signal transmission in a wide range of applications, including telecommunications, test equipment, and wireless systems. The connector’s construction features a durable, gold-plated copper body that provides excellent corrosion resistance and ensures long-term durability, even in demanding environments. This connector is designed for 50 Ohm impedance systems and delivers exceptional electrical performance across a broad frequency range from DC to 6 GHz, boasting a low VSWR of 1.30:1 for minimal signal reflection. Inside, a gold-plated phosphor bronze contact ensures maximum conductivity, while the high-grade TEFLON insulator provides low-loss characteristics and maintains signal integrity. The solder termination method allows for a secure and robust connection to your coaxial cable, creating a stable and lasting link. Capable of operating in extreme conditions with a temperature range of -65°C to 155°C, this connector is built for reliability.
