Introduction

The E21-400G30S is a pure hardware RF medium-power amplifier operating in the 410–470 MHz band, with a maximum output power of 1W. The module features a built-in LNA to significantly extend wireless communication range. Its high-efficiency, low-temperature-rise design supports continuous transmission at +50℃ ambient temperature. The integrated LNA, filter, and limiter provide a low noise figure to enhance receive channel sensitivity. The ultra-low power consumption design features a standby current of only 3uA, with simple control requiring just two I/O ports for TX/RX switching. The SMT design offers an ultra-compact form factor for easy integration. The entire solution is designed to industrial-grade standards, delivering high stability, long transmission range, and strong penetration and diffraction capability across a wide range of applications.
