Thread vs Flange RF Connector Comparison

2026-01-07

Threaded connectors and flange connectors are two core connection structures for RF connectors, with distinct differences in applicable scenarios and performance characteristics, which are critical for matching passive components like power splitters, couplers and loads.

Threaded RF Connectors

Connection Method: Fastened by rotating internal and external threads; some come with anti-loosening gaskets.
Key Advantages: Compact size, easy one-hand operation, and cost-effective.
Typical Models: N-type, SMA-type, 7/16 DIN-type.
Ideal Scenarios: Indoor low-to-medium power RF systems, laboratory testing, and outdoor base station passive components with moderate vibration resistance requirements.

Flange RF Connectors

Connection Method: Secured by flange plates and bolts, with precise end-face fitting.
Key Advantages: Superior shielding performance, ultra-high power capacity, and excellent vibration resistance.
Typical Models: Waveguide flanges, high-power coaxial flanges.
Ideal Scenarios: Millimeter-wave radar systems, high-power microwave transmitters, and equipment operating in strong vibration environments.

Core Difference Summary

Threaded connectors prioritize portability and ease of use, suitable for most general RF applications. Flange connectors excel in high-power and high-frequency scenarios, where stability and shielding are essential, despite being bulkier and requiring tools for installation.
