ZCG Scalar’s SMA RF adaptors provide high-precision coaxial interconnection solutions for RF, microwave, and communication systems, supporting frequencies from DC up to 18 GHz depending on configuration. This range includes both intra-series and inter-series SMA adaptors, enabling seamless conversion between SMA interfaces and a wide range of RF connector types including BNC, N-type, TNC, SMB, SMC, UHF, FME, and reverse polarity variants, ensuring flexible integration across diverse RF systems.
Designed for low insertion loss, stable 50 Ohm impedance, and excellent high-frequency performance, SMA adaptors are widely used in telecommunications, test and measurement, RF development, and wireless communication systems. Their compact threaded interface provides a secure mechanical connection while maintaining consistent electrical performance, even in high-vibration or space-constrained environments.
Manufactured using precision-machined brass bodies with high-quality nickel or gold plating, ZCG Scalar SMA adaptors are engineered for reliable long-term operation, excellent conductivity, and minimal signal degradation. Available in straight, right-angle, and bulkhead configurations, they provide a practical solution for system integration where RF interface conversion is required without introducing unnecessary loss or complexity.
