High reflected rf power
WebJul 7, 2024 · Fig 3: The reflected power can be seen as standing waves of current and voltage along the transmission line. (Image: Electronics Notes) Q: What’s the underlying theory? A: Transmission line impedance, propagation, matching, and related issue have been extensively studied and analyzed as they are very important topics. In simplified form: WebMay 22, 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 33 dB, the filter has a loss of 2.2 dB, and of the power input to the antenna, 45% is lost as heat due to resistive losses. If the power input to the amplifier is 1 W, then: Figure 1.3.2
