Introduction
RG402 Coaxial Cable is a high-performance, semi-rigid RF coaxial cable that is commonly used in microwave, RF, aerospace, defense, and test and measurement applications. RG402 is known for its good shielding, minimal signal loss, and mechanical stability, making it perfect for high-frequency signal transmission when reliability and precision are critical.
Unlike Flexible Coaxial Cables, RG402 has a solid copper outer conductor, making it ideal for fixed applications requiring reliable electrical performance.
What is RG402 Coaxial Cable ?
The RG402 is a 50-ohm semi-rigid coaxial cable with a solid copper jacket, PTFE dielectric, and a silver-plated copper center conductor. It is capable of operating at frequencies of up to 18 GHz, making it ideal for microwave and RF applications.
Once bent and curved, RG402 preserves its shape, resulting in steady impedance and low signal distortion.
Types of RG402 Coaxial Cables :
RG402 cables are primarily characterized according to jacket material and compliance standards:
1. Standard RG402 (Commercial Grade)
- Solid copper outer conductor.
- PTFE dielectric
- Used in radio frequency laboratory, telecom systems, and industrial electronics.
2. RG402 Mil-Spec (MIL-C-17)
- Manufactured to military specifications
- Increased dimensional precision and electrical stability
- Used in defense, aerospace, and satellite systems.
3. RG402 Cable Assembly
- Pre-terminated with SMA, SMB, MCX, or customized RF connections.
- Available in straight and right-angle designs.
- Suitable for plug-and-play RF modules.
