SD20/SP20 Square Flange Connector Design and Installation Guide

Choosing an N Series RF Connector for Dual-Band 4G/5G Base Stations

For integrated 4G/5G base stations, the N series RF connector is a suitable choice for dual-band compatibility. Its broad frequency range and robust mechanical design address the key requirements of modern, multi-band communication infrastructure.

Key Selection Criteria for Dual-Band RF Connectors

When evaluating connectors for this application, focus on these core decision points:

• Frequency Range: The connector must support both the 4G band (e.g., 1.8GHz) and the 5G band (e.g., 3.5GHz) with minimal signal loss.
• Voltage Standing Wave Ratio (VSWR): A lower VSWR indicates better impedance matching and less signal reflection, which is critical for maintaining signal integrity.
• Environmental Durability: Base stations are often deployed outdoors, requiring connectors that can withstand vibration and temperature variations.
• Installation Security: A reliable locking mechanism is essential to prevent disconnection due to vibration or wind load.

N Series Connector Specifications for 4G/5G Integration

The N series connector meets the demands of dual-band operation with the following verified parameters:

• Operating Frequency: ≤18GHz, which covers the 4G 1.8GHz and 5G 3.5GHz frequency bands.
• VSWR: ≤1.3, ensuring efficient signal transmission across the specified bands.
• Locking Mechanism: Threaded coupling with a specified torque of 0.5~0.8N·m for a firm and secure connection.
• Vibration Resistance: Designed to withstand 5g vibration, making it suitable for outdoor base station environments.

Application Fit and Installation Notes

This connector is designed to be compatible with both 4G and 5G RF modules, allowing for a single connector type across the system. This compatibility can help reduce the complexity and cost associated with base station upgrades or new installations. The threaded locking design ensures a stable connection that resists loosening from mechanical stress.

For installation, it is important to apply the correct torque (0.5~0.8N·m) to achieve the specified performance and environmental sealing. Over-tightening or under-tightening can affect the connector's reliability and electrical characteristics.

Inquiry Checklist for Your Project

To ensure the N series connector is the right fit for your specific project, please verify the following:

• Confirm the exact frequency bands and power levels required by your base station design.
• Specify the cable type and size to be used with the connector.
• Detail the environmental conditions, including temperature range and exposure to moisture or chemicals.
• Clarify the required mating cycles and any specific mechanical testing standards.
