5.2GHz Cavity Filter – Compact SMA Female Bandpass Module with DC Short Protection for WLAN Radio Units, High-Speed Base Stations & Industrial Communication Hardware

Product Description

In high-density indoor 5GHz environments, WLAN radio units and industrial communication base stations are frequently exposed to adjacent channel interference and electrostatic discharge. The 5.2GHz Cavity Filter is engineered to protect sensitive receiver front-ends while maintaining an ultra-slim profile for space-constrained equipment integration. Covering the 5150-5350MHz passband, this filter features a robust 50W power handling capacity, DC Short port protection, and SMA Female connectors to ensure reliable, low-loss connections. Housed in a rugged black aluminum enclosure, it effectively blocks spurious signals and preserves your link budget, making it an ideal drop-in component for high-speed wireless base stations and industrial-grade short-range communication hardware.

Typical Applications

• 5.2GHz WLAN Radio Units: Suppress out-of-band interference to maintain stable high-speed wireless coverage.
• High-Speed Wireless Base Stations: Protect receiver front-ends from high-power adjacent transmitters.
• Industrial Short-Range Communications: Enhance signal purity for reliable factory automation and control links.
• Indoor Dense-Scale Networks: Isolate operating bands from external noise in crowded indoor RF environments.
• Point-to-Point 5GHz Links: Improve the signal-to-noise ratio for fixed wireless backhaul systems.
• RF Testing & Diagnostics: Provide precise bandpass filtering for laboratory validation and field troubleshooting.
