LoRa 4MHz-wide Cavity Filter

A premium LoRa 900MHz-related band cavity filter that provides low-loss filtering of 900-915 MHz LoRa signals between an antenna and a LoRa device. Increases signal SNR, reduces out of band harmonics, and allows for the weaker and distant nodes to be heard. The Airframes LoRa Cavity Filter is Ideal for Meshtastic, Meshcore, etc. This could be used for non-Meshtastic uses. You can contact us if you need a cavity filter for your specific frequency needs that is not in the list (and we can likely accommodate for an extra fee). You cannot tune this filter to other CFs.

We have field tested these units and have seen great results, with a +20 to general SNR improvement. Reviews from the last 12 batches have been incredibly positive, and those running towers, mountains, or key city locations have benefitted the most.

We have recently arranged for mixed-frequency batches and increased batch size with our manufacturer. This means that we expect to be able to more rapidly ship out orders (and do not expect extensive wait times).
