Product Overview
The BT-PA150M-38M10W-RS485-SMA is a 10W RF power amplifier module designed to amplify radio frequency signals within the 136–174MHz frequency range. With a 38MHz bandwidth, up to 50dB gain, and SMA RF connectors, it provides an RF amplification solution for wireless communication equipment manufacturers and system integrators.
The module amplifies RF input signals to a maximum output power of 40dBm. Its adjustable gain function supports a gain adjustment range of at least 25dB, while automatic level control (ALC) helps regulate output levels. These features support RF signal amplification and output management within a communication system.
Designed for system integration, the module supports RS485 configuration, status monitoring, and alarm reporting. It provides forward and reverse power monitoring, temperature detection, VSWR monitoring, and automatic shutdown under over-temperature conditions. Its compact 200 × 140 × 25mm dimensions and no-extra-circulator design simplify integration into compatible RF systems.
