Just to note that transmitters are designed to drive a certain load impedance (often 50 Ω), but their internal source impedance is much lower than that specified load impedance. If it equaled the load impedance, then 50% of the output power generated by the final r-f amplifier in the transmitter would be dissipated as heat, within the transmitter. | |
