JMT Two-Way Lora Signal Booster, 863-870Mhz + 902-928Mhz Power Signal Amplifier Module WiFi Range Extender Transmitting & Receiving for Lora Router Ethernet RC Drone Europe 863MHz-870MHz, US M902Mhz-928Mhz frequency bands. Features: 1) This 868MHz signal amplifier module is a two-way amplified TDD working mode ,that is the transmit power and receiving sensitivity will be amplified equally. 2) The receiving/sending link has a high degree of isolation, and the receiving link can withstand strong external interference without causing self-excitation of the loop. 3) Compatible with various modulation methods such as LORA and FSK/ASK/OOK/MSK/GFSK. Basic Parameter: 1. Receiving gain: 11dB±2dB 2. Receiving noise figure: at most 2.0dB 3. Transmission gain: 5dB – 11dB (±2dB) adjustable 4. Recognition threshold for receiving and sending switching: -2dBm 5. Input power range: 1dBm-25dBm 6. Operating Voltage:The power supply voltage can be between 3.6V-6.0V, maximum transmission power increases as the supply voltage increases. 7. Maximum transmit power:31.5dBm (1.4w) at 3.7V supply voltage; 33.5dBm (2.3w) at 5.0V supply voltage; 34.5dBm (2.8w) at 6.0V supply voltage Work status indication: - Receiving : green light is on, blue light is off - Transmitting : blue light is on, green light is off - In TDD working mode, the blue light and green light will flash alternately Working current: RX status: 10mA (±3mA) TX status: at most 800mA (3.7v power supply); at most 1000mA(5.0v power supply); at most 1500mA (6.0v power supply)
