## Description

desertcart.com: Xiegu XPA125B 100W Power Amplifier Auto Antenna Tuner Large Display Screen : Electronics

Review: XPA125B with IC-705 Radio, Works Great! - Great Amp for the price. Antenna tuner works great if properly configured (refer to attached photo for tuning instructions). I am using it with my IC-705 and can get about 100W output with about 1W drive. Based on comments from others, the drive level may vary to get full output, but it seems to always give full output with 5W or less drive. I wanted to use this amplifier for POTA and ARRL Field Day use. I don't like to move my base radio, so I grab the IC-705 and XPA125B for all my outdoor or field day work! For POTA, it was always frustrating when someone could not hear me with 5W output. With the XPA125B, I always seem to make reliable contacts. As mentioned in prior reviews, the XPA125B will not automatically switch bands, you must remember to manually switch the band on the amp by pressing the "BAND" button. This is more of an inconvenience and not a problem for me. Typically, I am not "band jumping" anyway. Once I get my antenna up and tuned, I will typically remain on that band for my outing. I researched several other amplifiers in the 100W range before buying the XPA125B. Most other amplifiers did not have an ATU and if they did, the cost was much higher. Please refer to the attached photo of the ATU tuning instructions I created. The XPA125B tuner has worked great for me, but you must follow the tuning instructions to get everything tuned properly (the manual does not cover this very well).
Review: Dependable Linear… ATU LACKING. - ATU NEEDS redesign. Linear works great! Very small of input wattage provides great output wattage. 1 watt in provides 50 watts output.

## Features

- Built-in Automatic Antenna Tuner: The automatic antenna tuner and power amplifier unit of XPA125B can be used independently of each other as either an automatic antenna tuner or a separate power amplifier. The tuner handles 14-500 ohm loads in the HF bands and 6-meter band.
- 100W Power Output: The XPA-125B is the perfect amplifier for QRP radios or SDR transceivers with low power consumption （like a 5-watt transmitter） when 100-watt output is needed. Its maximum power output is 125 watts.
- Safty & Protection: The XPA125B has a variety of intelligent protection circuits to ensure the safety of the amplifier and connected transceiver. When abnormal operating conditions appear like SWR is too high, too much drive power, or too high temperature, the amplifier enters bypass mode and displays an alarm message.
- New Enhanced Version: After improving its shape and size from XPA125, it is smaller than the old version and can be worn on a bracelet like a small bag.
- Large Screen Display: The 2.7 inch large backlit LCD display shows input/output power, SWR, Voltage, Current, Temperature, amplifier status as well as warning messages making the operation of this modern amplifier simple and also user friendly.

### ⭐⭐⭐⭐⭐ Xiegu XPA 125B the little amp that could
*by K***R on October 25, 2025*

The Xiegu amplifier XPA125B is a marvelous unit that works great. Since buying it I've operated the amp on all bands but 6 meters. Excited by my G 90 and HL-2 transceiver. With about 1.5 Watts of drive the amp produces around 115 Watts out. I'm very happy with the unit. The fact it has a very robust antenna tuner is great as well. Before I bought the Xiegu amp I had tried several cheap no name amps that either failed after a short time or never worked from day one. Don't waste your money on the Noname brands get the Xiegu you will be happy you did.
