OGS-50W HF Power Amplifier 3-21Mhz RF Power Amplifier QRP Radio Power Amp OGS-50W 50W HF Power Amplifier for USDX FT-817 ICOM IC-703 IC-705 Elecraft KX3 QRP FT-818 G90 G90S G1M X5105 Ham AMP Description: 50W HF power amplifier is a powerful QSO tool in the field! It boasts small size, high communication efficiency and high power. Built-in automatic cooling fan will automatically stop rotating during standby to reduce wind noise. It also enables TX/RX automatic switching. When there is a signal input, it will automatically switch the transmission mode, without the need for a dedicated control line for your radio. Built-in TX/ auto cut circuit, no need for PTT , with signals input automatically switch to transmit mode. Built-in powerful fan, the temperature reaches the set value automatically open cooling, which can prolong the service time of the tool. This high frequency power amplifier is suitable for USDX FT-817, Elecraft KX3, QRP, FT-818, G90, G90S, G1M, X5105 Ham AMP. The operating frequnecy is 3~24MHz, and transmission and pulling power is 1~5W. Operating frequency: 3~24MHz Transmission and pulling power: 1~5W Specifications: – Input power: 1~5W – Output power: 40~60W – Working frequency: 3-21Mhz – Working voltage: 12V-13.8V Package Included: – 1 x Main Unit – 1 x Power Cable Note: – Before use, you need to use a NanoVna or similar tools to measure the antenna to 50Ω. The standing wave should be less than 1.5, otherwise the power amplifier tube will be burned due to the mismatch of the output!
