Xiegu GPA100 100W Linear Power Amplifier for HF Radio Transceivers | Compact Station Upgrade for Home Use, POTA, Field Day

High-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 bands 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

BT Wireless Band Control. Wirelessly connect your GPA100 to the IC-705 via built-in BT—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, 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
