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.

Band Bi-directional signal amplification

Technical Specification

Model：AB-89

Introduction

The AB-89 Series Bi-directional signal amplification module is suitable for micro-power wireless products in the frequency range of 850MHz-930MHz.

It is suitable for various IoT wireless data acquisition products working in the 850MHZ-930MHZ frequency band。

Main characteristics

1. Built-in TX/RX automatic switching circuit, TX/RX status can be switched independently without external control signal.

2. 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.

3. The TX gain is adjustable, which is convenient to be compatible with wireless devices with different transmission powers.

4. Compatible with various modulation methods such as LORA and FSK/ASK/OOK/MSK/GFSK.
