ABSTRACT:
A power amplification device for high-frequency amplitude-modulated signals comprises a first and a second amplifier employed respectively for amplification of a reduced-level HF modulated carrier signal and for amplification of the simple HF carrier signal extracted from the HF standard modulated signal and supplies in parallel the amplifier and a subtracter device through which the first amplifier receives the HF standard modulated signal. This results in excellent performances, high efficiency and stability, ease of maintenance and reliability.
