Optimized for Performance, Simplified for You
To minimize system insertion loss (often increased by multiple RF adapters), enhance overall sensitivity, and reduce noise, ACASOM has engineered two advanced filter variants for the 868MHz band: Type A and Type B. We ship Type A by default, offering an excellent balance of performance and value for most applications. If your project specifically requires Type B (e.g., for a different rejection curve or connector type), please leave us a message at checkout.

DESCRIPTION
Achieve cleaner signals and more reliable coverage with the ACASOM 868MHz Type A Cavity Filter. Precision-tuned for the 863-870MHz (7MHz bandwidth) spectrum, this filter is a critical upgrade for Helium Network hotspots and EU LoRaWAN IoT systems operating indoors. It delivers ultra-low insertion loss and provides effective out-of-band suppression starting at just 10MHz from the band edge, shielding your receiver from disruptive nearby interference. Built with a rugged aluminum housing, it includes integrated DC short circuit protection on its ports for basic surge suppression, safeguarding your connected equipment.

KEY FEATURES

  • Built-in Circuit Protection: Features DC short (surge/lightning arrestor) functionality on RF ports for added equipment safety.

  • Full Band Compatibility: Designed for the complete 863-870MHz EU LoRa application range.

  • Interference Reduction: Actively filters out-of-band noise to significantly improve signal-to-noise ratio and system performance.

  • High Efficiency Design: Ultra-low insertion loss (1.0dB nominal) ensures maximum signal strength is preserved.

  • Dual Application Ready: Ideal for optimizing both Helium Network hotspots and all 868MHz LoRa IoT gateways and sensors.
