5.8GHz Cavity Filter – High-Power SMA Female Bandpass Module for High-Speed Industrial Wireless & WLAN Base Stations

Product Description

In dense indoor wireless environments, high-speed WLAN base stations and industrial transmission hardware often face severe interference from adjacent 5GHz transmitters, alongside risks from static discharge. The 5.8GHz Cavity Filter is specifically engineered to resolve these challenges while handling high-power RF signals. Optimized for the 5700-5900MHz band, it features a robust 50W power handling capacity, DC Short port protection, and a wide operating temperature range. Its rugged black aluminum housing and secure SMA Female connectors make it an ideal, durable drop-in solution for protecting sensitive receiver front-ends and ensuring clean spectral performance in demanding wireless bridge and industrial communication integrations.

Typical Applications

• High-Speed Wireless Base Stations: Protect receiver front-ends from high-power adjacent transmitters in dense networks.
• 5.8GHz Wireless Bridges: Enhance signal purity for point-to-point and point-to-multipoint backhaul systems.
• Industrial Wireless Hardware: Suppress spurious emissions in high-speed factory automation and control links.
• Outdoor WLAN Equipment: Ensure spectral compliance and receiver protection for robust wireless deployments.
• Dense Indoor RF Environments: Isolate operating bands from external noise to maximize signal-to-noise ratio.
• RF Testing & Diagnostics: Provide precise bandpass filtering for laboratory validation and field troubleshooting.

Technical Specifications

Key Advantages

50W High-Power Handling with Wide Temperature Tolerance. Engineered for demanding industrial environments, this filter manages up to 50W of power and operates reliably across -40~80℃, ensuring stable performance under heavy RF loads and extreme temperature variations.

Optimized Passband and DC Short Protection. Covering a precise 5700-5900MHz range, it delivers ≤1.0dB insertion loss and VSWR ≤1.3. The built-in DC Short protection guards sensitive transceiver front-ends against static discharge or DC bias.

Rugged Compact Aluminum Construction. The ultra-slim 99*47*16.2mm black aluminum chassis provides excellent shielding and mechanical durability, while the standard SMA Female connectors ensure secure, low-loss integration into indoor wireless equipment.
