WebbTheir power output ratings are generally given at a certain frequency (often 1 kHz) into a common load (speaker impedance) of 4Ω, 8Ω, etc. It's critical to note that we do not need to match the amplifier's power output rating with the speaker's power handling rating. Webb21 mars 2024 · The output stage of an RF front end consists of an amplifier followed by a filter and then an antenna. The amplifier has a gain of , the filter has a loss of , and of the power input to the antenna, is lost as heat due to resistive losses. If the power input to the amplifier is , calculate the following: What is the power input to the amplifier?
