The Xiegu GPA100 is a solid-state linear amplifier that provides up to 100 watts of output power, designed to enhance amateur radio performance with reliable strength and user-friendly operation. It delivers clean, high-quality 100W output (80W on 6 meters) across a broad 1.8–54 MHz frequency range. With its advanced circuitry, the GPA100 offers improved efficiency and reduced distortion, ensuring excellent signal clarity for SSB and digital communications.

Features:

1. High-Efficiency Linear Power: Provides a clean and stable 100W output (80W on 6 meters) with excellent efficiency and minimal distortion. Its durable solid-state architecture delivers outstanding signal integrity, making it ideal for SSB and a wide range of digital modes—even under full load.
2. User-Friendly Band Control: Equipped with dedicated hardware buttons for seven amateur bands (1.8–50 MHz) and clear status LEDs that light up when a band is selected, allowing quick and accurate manual switching. For operators who change frequencies often, AUTO mode enables smooth, automatic band selection.
3. Smart Management & Full Protection: An intelligent control system and advanced cooling ensure stable performance. Built-in safeguards protect against high SWR, overheating, overcurrent, overpower, and low efficiency, with clear fault messages shown on the display for peace of mind.
4. Seamless Radio Compatibility: Optimized for integration with Xiegu transceivers like the G90, X6100, X6200, and IC-705, as well as other low-power (QRP) rigs. Supports both automatic band switching and ALC (Automatic Level Control) when connected.
5. Portable Yet Rugged Design: Engineered with a lightweight, space-efficient build for easy handling and transport. Suitable for permanent shack setups as well as portable and field operations.
6. Comprehensive Status Display: A bright LCD screen provides real-time monitoring of key parameters such as output power, SWR, operating mode (AUTO/MANUAL), selected band, input voltage, current draw, and internal temperature.
