Replacing RF coaxial connectors (such as SMA, N-type, BNC, etc.) requires compliance with strict performance standards, safety regulations, and industry practices to ensure signal integrity, impedance matching, and equipment reliability. 1. Hard standards for replacement (1). Electrical performance failure Standing wa...
READ MORERF glass insulator is an insulating support element used for high-frequency (RF) signal transmission. It is mainly made of special glass materials and has excellent high-frequency insulation performance, high temperature resistance and mechanical strength. It is widely used in communication base stations, radar systems...
READ MOREThe N-type RF coaxial connector is a universal threaded RF coaxial connector designed by Paul Neill of Bell Labs in the 1940s ("N" is taken from the first letter of his surname). It has the characteristics of high power, low loss, and high frequency, and is widely used in communications, radar, test instruments and oth...
READ MORERF coaxial connectors are key nodes in high-frequency signal transmission, and their installation quality directly impacts the performance of the entire communication system. They are typically used to connect two different interface types, ensuring signal transmission between connectors of different standards or sizes. RF coaxial adapters primarily serve to change connection methods, convert interface types, or adapt to devices with different frequency and impedance requirements. Ningbo Hansen Communication Technology Co., Ltd. is a manufacturer specializing in the production, processing, and trading of communications components, with over 30 years of experience in RF coaxial connectors, adapters, and cable assemblies. The company has developed its own machining, electroplating, and assembly shops, along with a stable and reliable network of suppliers.
1. Pre-Installation Preparations
Environmental Control Requirements:
The installation environment should maintain a stable temperature of 15-30°C and a relative humidity of ≤60%. The work area cleanliness level must meet ISO Class 6 standards. The work surface must meet anti-static requirements, with a surface resistivity within the range of 1×10⁴-1×10⁶Ω.
Tools and Testing Equipment:
High-precision torque wrench (±0.1 N·m)
End-face inspection microscope (magnification ≥40X)
Network analyzer (frequency range covers the test band)
Professional cleaning kit (includes anhydrous ethanol, dust-free cloth, etc.)
Connector Quality Inspection: Use optical inspection equipment to inspect the connector end face to ensure scratch depth is ≤0.05mm and that there are no visible surface contaminants. Contact resistance should be ≤1mΩ, and impedance matching tolerance should be within ±1Ω.
2. RF Coaxial Adapter Maintenance Guide
Cleaning and Maintenance
Clean the connector monthly with anhydrous ethanol (purity ≥99.7%) and a dust-free cloth. Treat stubborn stains with a dedicated RF connector cleaner. Maintain a single-direction wipe when cleaning (do not wipe in a rotating motion).
Contact Inspection
Check the elastic recovery of the center pin weekly. Observe contact surface wear using a 10x magnifying glass. Measure contact resistance (should be ≤2mΩ).
Protective Measures
Install a dust cap (IP54 rating) when not in use for extended periods.
Store in an ambient humidity ≤60% RH. Avoid storage with organic solvents.
