Amplifiers - HF

An HF amplifier used in amateur radio is an electronic device that boosts the power of high-frequency (HF) signals transmitted by amateur radio operators. It operates by taking a low-power input signal and amplifying it to a higher power level, typically measured in watts. HF amplifiers employ various circuit designs, such as solid-state (using transistors) or tube-based (using vacuum tubes), to amplify the signal and enhance its strength, enabling improved long-distance communication capabilities.
