RigExpert 915MHz Bi-directional Power Amplifiers are specialized devices designed for applications within the 915MHz Industrial, Scientific and Medical (ISM) band. Its primary function is to enhance signal strength in both transmit (TX) and receive (RX) modes. With a 5VDC power supply, this amplifier provides 20dB gain during receive and 15dB gain during transmit for RF signals from 6 to 126mW. Its versatility makes it suitable for various applications including Amateur Radio, software-defined radio (SDR), unmanned aerial vehicles (UAVs), Internet of Things (IoT) devices and laboratory equipment.
