Collection: 868MHz Cavity Filter

This 868MHz bandpass RF filter is designed for the European ISM 863–870MHz band, perfectly matched for Helium hotspot, LoRa, LoRaWAN, Sigfox and other LPWAN IoT devices. It retains valid 868MHz communication signals while effectively attenuating unwanted out-of-band noise and adjacent frequency interference, improving receiver sensitivity and extending wireless transmission distance.

This helium cavity filter adopts high-precision microwave structure, delivers low insertion loss and high stop-band rejection. Indoor and outdoor options are available. Standard 50 Ohm impedance with SMA/N connectors for simple installation between antenna and radio transceiver. Compact metal housing provides stable performance under different temperature environments for smart meter, sensor, gateway and remote monitoring systems.
