Description: 1PC 868/915MHz Bidirectional Signal Amplifier LORA Signal Reception Enhancement Bidirectional signal amplifier Features:1. Transmit gain 0-10db adjustable (factory default 0db)2. Receive gain 11db±2db3AB-89 (without filter 850-930MHz) universal Model：AB-868、AB-915 Introduction The AB-868、AB-915 Series Bi-directional signal amplification module is suitable for micro-power wireless products in the frequency range of 868MHz-870MHz（AB-868） 、902MHz-928MHz（AB-915）. A built in filter avoids interferences with out-of-band signals It is suitable for various IoT wireless data acquisition products working in the 868MHZ frequency band in Europe and the 902MHZ-928MHZ frequency band in North America. Main characteristics Built-in TX/RX automatic switching circuit, TX/RX status can be switched independently without external control signal. It works in RX status by default, and enhances the receiving signal. When the transmitting signal of the superior device is detected, the module instantly switches to the TX status. The TX gain is adjustable, which is convenient to be compatible with wireless devices with different transmission powers. Compatible with various modulation methods such as LORA and FSK/ASK/OOK/MSK/GFSK. Specifications Working frequency： AB-868：868MHz – 870MHz AB-915：902MHz – 928MHz RX gain： 11dB±2dB NF： ≤1.5dB TX gain： 0dB – 10dB (±2dB)Adjustable TX/RX switching threshold： -2dBm TX input power range： 1dBm - 31dBm Maximum transmit power： 31dBm (1.3w) Status indication ： RX status： Green light is on, Blue light is off TX status： Blue light is on, Green light is off Operating Voltage ： 5V（4.75V-5.25V） Working current ： RX status ：10mA（±3mA） TX status ：≤720mA Overall dimension : 79mm*64mm*23mm(L*W*H) Tips: The output power of the upper-level device must be at least 3dB higher than the switching threshold, which means that the output power of the upper-level device cannot be lower than 1dBm, otherwise it may cause unstable operation.
