OGS-50W HF QRP Power Amplifier 3-21MHz 50W RF Radio Signal Booster
Supercharge your portable QRP radio setup with the premium OGS-50W HF Power Amplifier. Specifically engineered for field operations and mobile stealth stations, this pocket-sized amplifier boosts lightweight 1–5W input signals up to a powerful 40–60W output across the 3–21MHz shortwave bands. Featuring highly advanced TX/RX automatic RF-sensing switching technology, the unit instantly toggles transmission modes the moment a signal enters the port—completely eliminating the need for a dedicated transceiver control PTT line.
Housed in a rugged, black-anodized aluminum alloy chassis, this high-efficiency radio tool is incredibly compact for seamless field deployment. An intelligent, temperature-controlled internal cooling fan runs dynamically during transmission and stops during standby, drastically reducing cabin wind noise during quiet monitoring sessions. Perfect for FT-817, FT-818, IC-705, KX3, and Xiegu G90 setups, it delivers reliable high-power gains exactly when you need them.
Key Features:
High-Power QRP Gain: Converts a low 1–5W input signal into a commanding 40–60W output to burst through poor propagation.
Smart RF-Sensing Switch: Features automatic TX/RX internal switching that triggers on input without external control cables.
Whisper-Quiet Thermal System: Built-in smart fan automatically stops rotating during radio standby to eliminate station noise.
Ruggedized Aluminum Body: Premium black-oxidized aluminum alloy enclosure shields delicate internal components from external interference.
Broad QRP Compatibility: The ideal field companion for popular portable rigs like the uSDR, USDX, FT-817/818, IC-703/705, KX3, and Xiegu transceivers.
⚠️ Crucial Technical Notice for Operators:
Before applying power, always verify that your connected external antenna system is properly tuned to 50Ω impedance using a NanoVNA or similar antenna analyzer. The voltage supply must sit strictly between 12V–13.8V DC. Running this high-frequency amplifier into an mismatched antenna array with a Standing Wave Ratio (SWR) higher than 1.5 can overheat and permanently damage the RF power amplifier tubes.
