What does a typical RF dummy load consist of?
Pick an answer to check it.
Answer: B. A 50-ohm non-inductive resistor mounted on a heat sink
A typical RF dummy load is a 50-ohm resistor that is non-inductive, so it looks like a perfect 50-ohm antenna. It is mounted on a heat sink because it turns the transmitter's power into heat.
Tip: 50 ohms, no inductance, plus a heat sink.
