I don't believe this is true, AF and RF have significant overlap on the frequency domain, AF is just baseband RF when it's on the wire. RF very much can work with a resistive load, a 50ohm dummy load will ohm out as 50 ohm DC on any cheap multimeter.
- myself248 4y agoThe distinction is when the transmission line is "electrically short" relative to the wavelength of the highest harmonic of interest (typical in audio unless your speaker wires are 40km long), and thus its impedance doesn't play much of a role (and therefore you "see" the load directly), or if the transmission line is "electrically long" (typically the case in RF), so your source is driving the line rather than driving the load directly.
