SMA Straight Crimp Cable Type Plug Connector 50 Ohm
The SMA connector is engineered for stable RF performance and secure cable attachment. With a straight orientation and crimp termination, it ensures reliable installation while maintaining excellent signal integrity across a frequency range of DC to 6 GHz.
Built with a copper body and gold plating, this connector provides superior conductivity and durability. The phosphor bronze contacts with gold plating reduce resistance and enhance performance, while the Teflon insulation delivers thermal stability. Designed to operate from -65°C to +155°C with a low VSWR of 1.30:1, it is suitable for high-frequency, low-loss applications.
Key Features:
- Straight SMA plug, crimp termination
- Frequency range: DC–6 GHz, VSWR 1.30:1
- Copper body with gold plating
- Phosphor bronze contacts, gold-plated
- Teflon insulation, wide temperature range
