Hand-formable 085-alternative RG402 semi-flexible 50 Ohm coaxial cable with a high-isolation tin-soaked copper braid shield (>100 dB) and solid PTFE dielectric, offering seamless solid-tube shielding and flat attenuation from DC to 18 GHz for cabinet routing, radar modules, and aerospace payloads.
The RG402 coaxial cable by Zhenjiang Worldpeak is a high-performance semi flexible coaxial cable engineered to deliver solid-tube shielding with hand-formable convenience. Built with a high-durability tin soaked copper braid outer conductor, this premium 50 ohm semi flexible cable provides exceptional shielding effectiveness exceeding 100 dB. Featuring a 0.92 mm solid SPCCS core and a 2.98 mm solid PTFE dielectric, it acts as an outstanding alternative to standard .141 semi rigid cable designs. It is the ideal transmission choice for high-frequency RF routing inside communication enclosures, radar modules, and aerospace payloads from DC to 18 GHz.
In high-frequency RF system designs, mitigating electromagnetic interference while optimizing path routing is critical. The Zhenjiang Worldpeak RG402 coaxial cable is engineered specifically to address these challenges, combining the excellent shielding of a rigid solid-jacketed cable with the practical routing versatility of a flexible coax. Utilizing a premium tin soaked copper braid outer conductor, this semi flexible coaxial cable acts as a near-solid metal tube to eliminate RF leakage and crosstalk.
Standard braided shield lines often suffer from signal leakage at higher microwave frequencies. However, the unique tin-filled braid geometry of this 50 ohm semi flexible cable provides a continuous electrical barrier, achieving a solid-tube equivalent isolation rating of over 100 dB. For RF engineers seeking high-frequency performance without the tooling challenges of a conventional .141 semi rigid cable, the Zhenjiang Worldpeak RG402 coaxial cable serves as a reliable, high-integrity signal path that can be formed and installed quickly on the production floor.
Exceptional Shielding Efficiency: The specialized tin soaked copper braid delivers over 100 dB of RF isolation, making this RG402 coaxial cable ideal for dense high-frequency assemblies.
Hand-Formable Convenience: This semi flexible coaxial cable can be bent into position manually during system assembly, eliminating the expensive bending tools required for standard .141 semi rigid cable.
High-Frequency Capabilities: It provides flat, predictable attenuation profiles from DC up to 18 GHz, maintaining stable electrical length under varied conditions.
Wide Temperature Resilience: Operates smoothly between -55°C and +125°C, ensuring high performance in military electronic bays and outdoor communication base stations.
Optional Protective FEP Jacket: Available with a translucent FEP outer jacket to protect the raw tin soaked copper braid from oxidation, salt spray, and mechanical abrasion.
Manufacturing a premium 50 ohm semi flexible cable requires strict control over metallurgic and thermal properties to guarantee performance:
Precision Solder Bath Sintering: To manufacture this semi flexible coaxial cable, Zhenjiang Worldpeak passes a high-purity tinned copper braid through a precisely controlled tin bath. This process must be perfectly monitored: if the temperature is too low, the tin fails to fill the spaces in the braid, degrading shielding; if it is too high, the tin compromises the PTFE dielectric interface. Zhenjiang Worldpeak utilizes automated temperature-feedback machinery to maintain absolute uniformity.
Work-Hardening Mitigation: While this semi flexible coaxial cable offers hand-formability, the outer shield work-hardens with repetitive bending. Zhenjiang Worldpeak has engineered the metallurgical composition of the tin soaked copper braid to maximize its initial ductility, ensuring reliable single-bend shape retention during installation.
Impedance Continuity: By maintaining strict outer diameter tolerances (3.58 mm) and core conductor concentricity, this RG402 coaxial cable eliminates reflection spikes, delivering outstanding return loss performance up to 18 GHz.

Q: Can this RG402 coaxial cable be bent multiple times during installation?
A: No, this semi flexible coaxial cable is designed for a "set-and-forget" deployment. The tin soaked copper braid work-hardens when bent. Repeated bending at the same point will introduce micro-cracks in the tin layer, which degrades shielding performance and physical integrity.
Q: What is the benefit of choosing this cable over a standard .141 semi rigid cable?
A: A traditional .141 semi rigid cable requires complex CNC bending tools and precise routing blueprints. The Zhenjiang Worldpeak RG402 coaxial cable provides identical shielding performance but can be bent by hand during prototyping or system integration, dramatically reducing assembly time and tooling costs.
Q: Is there an option with an FEP jacket?
A: Yes, Zhenjiang Worldpeak offers both bare-braid and FEP-jacketed versions. The FEP jacket adds outstanding environmental protection against moisture, salt spray, and chemicals, raising the overall cable diameter to 4.10 mm.
