This cavity bandpass filter is specially designed for the LoRa / Helium frequency band and impresses with its very good technical parameters. By using this filter, interfering signals from other frequency bands, such as the 4G 800MHz frequency band, are filtered out and attenuated very efficiently. In this way, signals from much greater distances can be received and processed with little interference. Especially the good signal suppression and the low insertion loss of less then 1dB perform extremely well with this model. Compared to a SAW filter, this cavity filter has significantly better performance and delivers a much better result.
The filter is connected between antenna and miner/access point or between antenna and booster/amplifier and thus efficiently and cleanly filters out interfering signals. The filter is intended for indoor use, but can also be placed outdoors, for example by being housed in a housing, and connected directly to the helium antenna.
