L-Band RF Front-End Module with PA, LNA & High-Speed T/R Switch (1100–1500MHz)

Overview

The L-Band RF Front-End Module is a compact, high-performance RF solution integrating a power amplifier (PA), low-noise amplifier (LNA), and a high-speed transmit/receive (T/R) switch in a single enclosure. Operating across the 1100–1500 MHz frequency band, it is designed to significantly extend communication range, improve link robustness, and enhance signal quality for Mesh radios, COFDM systems, and SDR platforms.

With a 33 dBm RF output power, low EVM performance, and microsecond-level TX/RX switching speed, this module is optimized for time-division duplex (TDD) communication systems. Its lightweight and compact design makes it ideal for UAVs, mobile mesh nodes, and tactical communication applications where size, weight, and reliability are critical.
