Xiegu XPA125B HF Linear Amplifier with ATU 100W, 0.5–54MHz

Xiegu XPA125B HF Linear Amplifier with Built-in ATU

The Xiegu XPA125B is a compact, all-solid-state 100W HF linear amplifier with a built-in automatic antenna tuner (ATU), designed to pair seamlessly with Xiegu QRP transceivers including the X5105, X108G, G90 and G1M. Covering 0.5 to 54MHz, it transforms a low-power portable rig into a capable 100W+ station with minimal setup. The CNC-machined chassis includes comprehensive input and output protection, making it a reliable choice for both home and field use.
