YR-AMP868-A two-way LoRa signal amplifier is suitable for low-power wireless products in the frequency range of 863MHz~870MHz(typical frequency: 868MHz). This product is ultra-thin in size, simple in the periphery, and has three built-in waterproof rings, conforms to IP67. It can be used in EU 863MHz~870MHz wireless data acquisition systems..

Mainly used in various occasions in 420MHz-480MHz frequency band that have special requirements for signal transmission distance and connection stability, such as 433MHz remote control aircraft, 433MHz wireless data acquisition system, Lora products. presence of the wanted signal and an interfering signal reaching the transmitter via the antenna. The intermodulation products (IP) are mainly generated by the single pole double throw (SPDT) and power amplifier (PA), as nonlinear components, in the presence of both the transmit (Tx) signal and reverse interfering signal.

The RF 868MHz is a public bandwidth European Low Power Networks (LPWAN) as Sigfox and LoRaWan are using for communicating. This bandwidth is regulated by different norms like ERC-REC-70-3E in Europe and have national norms in relation. In France ARCEP 2014-1263 seems to be the last one validated in the JO on the 30th of January 2015. I have another problem with the Heltec boards: The LoRa transmission breaks completely after a random time when I send packets from a background task. From then on, all transmissions become erroneous until the board is restarted. The signal doesn't look reasonable even over SDR. The transmissions themselves also take almost no time at all.
