SMA 4-Hole Flange-Mounted Receptacle: Robust RF Coaxial Connector for Stable High-Frequency Transmissionf

Product Analysis
The SMA series connectors are benchmark products in the field of RF connectivity, boasting the dual advantages of a compact structure and a threaded coupling mechanism. Their precision-threaded design enables reliable locking, ensuring consistent connection status. As a classic solution in RF connectivity, they are specifically designed for RF circuits in digital communication systems and microwave equipment, undertaking the critical task of signal connection for microstrip lines or cables, and providing a solid guarantee for high-frequency signal transmission.

Applicable Scenarios

Widely covering telecommunications networks, data transmission, and wireless communication systems, they are particularly well-suited for scenarios with strict requirements on connection reliability and space utilization — from high-density wiring in base station equipment rooms, to miniaturized designs of drone communication modules, and to precision connections in medical microwave equipment, they can stably perform.

Core Advantages

  • Innovative Locking Performance: The threaded coupling structure achieves "micron-level" docking accuracy, combined with the reinforced fixing effect of flange mounting, which can withstand continuous vibration and temperature fluctuations. It maintains connection stability under working conditions from -55℃ to 125℃, far exceeding the industry average standard.
  • Full-Frequency Band Performance Guarantee: Maintains extremely low VSWR (≤1.2) and insertion loss (≤0.15dB) over a wide frequency range (DC to 18GHz), with a signal transmission fidelity of 99.9%, perfectly adapting to high-frequency applications such as 5G millimeter waves and satellite communications.
  • Long-Lasting and Durable Nature: Adopts military-grade plating technology and high-strength alloy materials. After more than 500 insertion and extraction cycles, the electrical parameters remain stable, significantly reducing the maintenance frequency and costs throughout the equipment's life cycle.
  • Maximized Space Efficiency: The volume is 40% smaller than traditional N-type connectors, enabling 16-channel parallel installation in a 1U height chassis, providing a high-density connection solution for modular equipment.
