Xiegu GPA100 is a 100W solid-state linear power amplifier engineered to elevate your amateur radio operations with robust power and intuitive control. The GPA100 delivers a clean, high-fidelity 100-watt output (80W on 6 meters) across a wide frequency range from 1.8 to 54 MHz. Its advanced circuit design ensures lower distortion and higher efficiency, providing exceptional signal quality essential for SSB and digital modes.

Designed for the active amateur, the GPA100 distinguishes itself with a streamlined, cost-effective approach compared to its counterparts like the Xiegu XPA125B, by focusing purely on amplification without an integrated antenna tuner. This allows for greater flexibility if you already own a separate ATU or prefer a dedicated amplifier. Operators will appreciate the direct and simplified control experience offered by its array of dedicated physical buttons for seven frequency bands, each with an illuminating indicator for quick visual confirmation. For convenience, an "AUTO" mode is also available, providing automatic band switching.

The GPA100 is highly compatible with a range of hf transceivers, including the Xiegu G90, X6100, X6200, and Icom IC-705, as well as other low-power (QRP) radios, supporting seamless integration with automatic band switching and Automatic Level Control (ALC) capabilities. Equipped with a comprehensive protection system covering high SWR, overcurrent, over-temperature, low efficiency, and overpower, the GPA100 ensures reliable and safe operation. Its compact and lightweight design makes it an excellent choice for both permanent shack installations and portable field deployments, providing powerful amplification wherever your adventures take you.
