Product Description

RG402 M17/130 is a MIL-DTL-17 qualified 50 Ohm semi-rigid coaxial cable engineered for microwave and millimeter-wave applications demanding absolute signal integrity. Unlike flexible braided cables, this precision transmission line features a solid copper tube outer conductor that provides 100% RF shielding and maintains precise spacing between center conductor and dielectric. The result is exceptional impedance control, phase stability, and the lowest possible insertion loss through 20 GHz. With shielding effectiveness exceeding 110 dB, RG402 effectively eliminates electromagnetic interference in sensitive receiver systems and test environments. The PTFE dielectric and silver-plated copper-clad steel center conductor deliver consistent performance across -55°C to +150°C, making it the go-to choice for radar systems, satellite communications, and precision laboratory measurements where cable-induced phase error cannot be tolerated.

Key Features
  • Solid copper tube outer conductor – 3.58mm diameter seamless tube provides 100% RF shielding with no braid gaps or signal leakage
  • 20 GHz frequency capability – Rated for continuous operation through 20 GHz for demanding microwave applications
  • 110 dB shielding effectiveness – Complete isolation from external interference, essential for sensitive receivers and EMC-critical installations
  • Phase-stable construction – Rigid geometry maintains electrical length and phase relationship regardless of vibration or temperature cycling
  • PTFE dielectric – Low loss material with 70% velocity factor ensures minimal signal degradation at high frequencies
  • Silver-plated copper-clad steel center conductor – 0.92mm diameter SCCS provides strength and stable conductivity for precision assemblies
  • MIL-DTL-17 qualified – M17/130 for defense and aerospace applications requiring full traceability
  • 0.141 inch form factor – Industry-standard diameter compatible with a vast ecosystem of connectors and assembly tools

Applications
  • Microwave test equipment – Interconnects for vector network analyzers, signal generators, and spectrum analyzers through 20 GHz
  • Radar systems – Air traffic control, weather surveillance, and defense radar requiring phase-stable transmission lines
  • Satellite ground terminals – Low-loss feeder lines for uplink and downlink equipment through Ku-band
  • Telecom backhaul – Microwave radio connections requiring stable electrical performance
  • Aerospace telemetry – Phase-critical links between antennas and processing electronics
  • Electronic warfare – 100% shielding prevents detection and interference in sensitive receiver chains
  • Medical imaging – MRI and RF ablation systems where cable stability is essential
  • Calibration laboratories – Reference grade cable assemblies for precision measurements
  • Defense systems – MIL-DTL-17 compliant for mission-critical applications
  • Antenna feed networks – Phased array and beamforming systems requiring consistent electrical length
FAQ
Q: What makes RG402 different from flexible coaxial cables like RG316 or RG400?
A: RG402 uses a solid copper tube outer conductor rather than braided shielding. This provides 100% RF coverage, superior phase stability, and lower loss at microwave frequencies, but the cable is semi-rigid and must be formed to shape before installation.
Q: What is the correct M17 designation for RG402?
A: M17/130 is the official MIL-DTL-17 part number.
Q: What is the maximum frequency for RG402?
A: 20 GHz, with mode-free operation throughout the range.
Q: What is the outer diameter?
A: 3.58mm (0.141 inches), which is the industry standard for this class of semi-rigid cable.
Q: Can RG402 be bent after installation?
A: Semi-rigid cables are designed to be formed once. Repeated bending or reforming can work-harden the copper tube and cause cracks or impedance variations. Specialized forming tools are recommended.
Q: What connectors are used with RG402?
A: SMA, 2.92mm (K), 3.5mm, N-Type, and TNC connectors designed for 0.141 inch semi-rigid cable. Connectors are typically soldered or clamped to the copper tube.
Q: Is RG402 suitable for outdoor use?
A: Bare copper versions require protection from moisture and corrosion. Jacketed variants (FEP or PVC) are available for outdoor exposure.
Q: What is the shielding effectiveness?
A: >110 dB, meaning virtually no signal leaks in or out.
Q: What is the voltage rating?
A: Dielectric withstanding voltage is 5000V, with continuous operating voltage typically 1900V RMS.
Q: Do you offer custom lengths?
A: Yes, we are a RF coaxial cable manufacturer, accept OEM & ODM, RG402 is available in straight lengths cut to your specification. Pre-formed custom shapes and connectorized assemblies can also be manufactured to your drawing.
