Amplitec 4M/7M 868Mhz Cavity Filter For Helium Miner
To suppress interference signals outside the frequency bandwidth of the Lora wireless network.
The FL868-S20 Cavity Filter is a band-pass filter for Helium IoT, the main function is to suppress interference signals outside the frequency bandwidth of the Lora wireless network. Compared with RF SAW Filter, Cavity Filter has stronger out-of-band suppression capability and smaller insertion loss.
By adding an CFL868-S20 cavity filter at the service antenna position of Helium Miner, it can effectively improve the receiving sensitivity of Miner and increase the access capability by 3~5 times.
