YR-AMP868 868MHz Helium Signal Amplifier

YR-AMP868 868MHz Bidirectional LoRa Signal Amplifier

YR-AMP868 is a bidirectional LoRa signal amplifier designed for low-power wireless products operating in the frequency range of 863MHz to 870MHz (typical frequency: 868MHz). This ultra-slim amplifier is ideal for use in wireless data collection systems in the EU 863MHz to 870MHz range, such as Helium Hotspot Miner or LoRa gateways. It features 2 integrated SAW filters on the receiving channel, which effectively enhance performance and resilience against interference.

Performance Characteristics:

• Built-in smart discrimination circuit for reception/transmission that does not require connection to the front end for switching control signals.
• Adjustable transmitter gain from 0dB to 7dB for compatibility with various wireless devices. Receiver gain ranges from 9dB to 16dB.
• The receiving and transmitting channels have high isolation and are resistant to strong external interference without creating self-locking loops.
• Compatibility with LoRa, FSK / ASK / OOK / MSK / GFSK modulation modes and more.
