Optimised for use with Xiegu rigs including the G90, X6100, X6200 and the Icom IC-705, it supports both automatic and manual band switching with ALC integration. A bright LCD display provides real-time monitoring of power, SWR, temperature, voltage and current — making it equally at home in the shack or out in the field.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e100W output (80W on 6m) from low-power QRP input — clean, stable signal for SSB and digital modes\u003c\/li\u003e\n\u003cli\u003eAuto and manual band switching — seven bands (1.8–50MHz) with dedicated hardware buttons and status LEDs\u003c\/li\u003e\n\u003cli\u003eLCD display showing output power, SWR, band, mode, voltage, current and temperature in real time\u003c\/li\u003e\n\u003cli\u003eSmart protection: guards against high SWR, overheating, overcurrent, overpower and low efficiency\u003c\/li\u003e\n\u003cli\u003eALC support for seamless integration with compatible transceivers\u003c\/li\u003e\n\u003cli\u003eLightweight and portable — suitable for shack, portable and field operation\u003c\/li\u003e\n\u003cli\u003eCompatible with Xiegu G90, X6100, X6200 and Icom IC-705\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFrequency Range: 1.8–54MHz\u003c\/li\u003e\n\u003cli\u003eMax Output Power: 100W ±1dB (\u0026lt;29.7MHz) \/ 80W ±1dB (50–54MHz)\u003c\/li\u003e\n\u003cli\u003eOverall Gain: 14dB ±1dB (\u0026lt;29.7MHz) \/ 12dB ±1dB (50–54MHz)\u003c\/li\u003e\n\u003cli\u003eSpurious Suppression: ≥50dB\u003c\/li\u003e\n\u003cli\u003eSupply Voltage: 12.0–15.0V DC (negative ground)\u003c\/li\u003e\n\u003cli\u003eStandby Current: 300mA max\u003c\/li\u003e\n\u003cli\u003eTX Current: 25A max\u003c\/li\u003e\n\u003cli\u003eMax Operating Temperature: ≤55°C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Xiegu","offers":[{"title":"Default Title","offer_id":57522914132312,"sku":"MOON-99-888","price":469.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/8753\/5192\/files\/gpa_1.png?v=1781608393","url":"https:\/\/kamsat.co.uk\/products\/xiegu-gpa100-100w-linear-amplifier","provider":"Kamsat","version":"1.0","type":"link"}
