50W HF Power Amplifier for USDX uSDR FT-817 ICOM IC-703 IC-705 IC705 Elecraft KX3 QRP FT-818 Xiegu G90 G90S G1M X5105 G106 Ham AMP

Built-in TX/RX auto cut circuit, no need for special PTT line, with signal input automatically switch to transmit mode. Built-in powerful fan, the temperature reaches the set value automatically open cooling.

Parameters

• Transmission and input power: 1～5W.
• Output power: 50W.
• Interface impedance: 50Ω.
• Operating voltage: 13.8V.

Attention

Before use, you need to use nanoVNA or similar tools to determine the transmitting antenna impedance of 50Ω, SWR < 1.5. Otherwise, the power transmitter tube will be damaged due to the mismatch of transmitting

impedance!
