The Xiegu GPA100 is a next-generation 100W HF/6m solid-state linear amplifier built for ham radio operators who demand clean power, wireless control, and long-term reliability. Featuring 7-band auto and manual switching (1.8–54 MHz), it delivers stable, high-quality output and superior signal integrity, even during extended operation. With built-in Bluetooth band control, the GPA100 pairs seamlessly with ICOM IC-705—no additional cable required. It also integrates perfectly with Xiegu G90, G1M, G106, X108G, X5105, X6100, and X6200, transforming your compact QRP radios into a powerful 100W station with full ALC and band data support. Whether you’re operating a home-based station, setting up in the field, or chasing DX during contests, the GPA100’s intelligent protection, advanced heat management, and wireless connectivity make it a dependable, high-performance amplifier for every amateur radio enthusiast. FeaturesHigh-Performance Linear Amplification: Experience clean, stable, and powerful RF output—up to 100W on HF and 80W on 6m. The solid-state linear design ensures low distortion, high efficiency, and exceptional signal purity, delivering crystal-clear performance across SSB, AM, FM, CW, and digital modes, even during extended transmissions. Flexible Band Switching: Easily select from 7 amateur bands (1.8–54 MHz) using manual buttons with clear indicator lights for instant feedback, or enable auto mode for seamless automatic band tracking—ideal for operators frequently moving between SSB, CW, and digital modes. Smart Cooling & Intelligent Protection: Advanced cooling and intelligent control automatically detect and protect against high SWR, overcurrent, overheating, low efficiency, and overpower—ensuring stable performance, longer lifespan, and safe operation even during long sessions. Bluetooth Wireless Band Control: Wirelessly connect your GPA100 to the ICOM IC-705 via built-in Bluetooth—no additional cable required. Enjoy automatic band switching for a fully cable-free setup, while unsupported bands are seamlessly bypassed for uninterrupted operation. Broad Transceiver Compatibility: Works perfectly with Xiegu G90, G1m, G106, X108G, X5105, X6100, X6200, ICOM IC-705, and other low-power transceivers (QRP). Easily expand your QRP setup into a 100W station with automatic band-synchronization and ALC (if supported by the radio) for safe, efficient amplification Clear Status Monitoring: A bright LCD provides real-time, comprehensive information on critical operating parameters, including output power, SWR, current operating mode (AUTO/MANUAL), active band, input voltage, current draw, and internal temperature.
