A transmission line is used to connect a source to a matched load, i.e. Zo = ZL. The power delivered to the load is 180 Watts. Then a Q dB attenuator and a 20 dB amplifier are inserted between the source and the load. a) Calculate the power delivered to the load in Watts (in linear scale) b) Calculate the power delivered to the load in dB scale. Notice that Pa = 10log10P c) Calculate the power delivered to the load in dBm scale.
