SMA Cable Assembly
SMA Cable Assemblies are high-performance RF cable solutions designed for stable signal transmission in telecom, wireless communication, RF, microwave, GPS, IoT, and testing applications. These assemblies use precision SMA connectors combined with low-loss coaxial cables to deliver reliable connectivity, low insertion loss, and excellent high-frequency performance across demanding RF environments.
At SRFS Teleinfra, we manufacture and supply premium-quality SMA Cable Assemblies engineered for accurate impedance matching, low VSWR, high shielding effectiveness, and long operational life. Our SMA cable assemblies are widely used in telecom systems, antenna connectivity, RF modules, wireless communication devices, laboratory testing, aerospace systems, and 4G/5G network infrastructure.
Our SMA assemblies are manufactured using high-grade RF coaxial cables such as RG58, RG174, RG316, LMR series cables, and precision SMA connectors to ensure stable signal transmission and durable mechanical performance. These assemblies are available in multiple connector configurations, cable types, and customized lengths according to project requirements.
What is an SMA Cable Assembly?
An SMA Cable Assembly is a coaxial RF cable fitted with SMA (SubMiniature Version A) connectors on one or both ends for high-frequency signal transmission. SMA connectors are widely known for their threaded locking mechanism, reliable RF performance, compact size, and ability to support microwave frequencies.
SMA cable assemblies are commonly used in RF communication systems where stable connectivity, low signal loss, and high-frequency operation are essential.
A typical RF cable consists of:
- Inner conductor (signal transmission)
- Dielectric insulation (maintains spacing and stability)
- Shielding layer (blocks interference)
- Outer jacket (provides protection)
