Q. A transmitter is connected to an antenna by a transmission line for which ¯ Z0 = R0 = 50 . The transmitter source impedance is matched tothe line, but the antenna is known to be unmatched and has a re?ection coef?cient
where RL (= ¯ ZL) is the load impedance. The transmitter produces a power of 15 kWin the incidentwave to the antenna andwill be destroyed due to overheat if the re?ected wave's power exceeds 2 kW. Determine the antenna's radiated power in this case and comment on whether the transmitter will survive.
Q. Illustrates typical thermal noise waveform? In general, any physical resistor or lossy device can be modeled by a noise source in series with a noiseless resistor, as shown
