For an antenna tuner of the "Transformer" type, which of the following statements is FALSE?
B
Answer
Interference, EMC, and safety
Type
A
The input is suitable for 50 ohm impedance
B
The circuit is known as a Pi-type antenna tuner
C
The output is suitable for impedances from low to high
D
The circuit is known as a transformer-type antenna tuner
Answer Notes
A transformer-type antenna tuner uses a magnetic coupling, or transformer, to match the standard 50-ohm output impedance of a transmitter to an antenna system whose impedance can range from very low to very high.
The false statement is that this circuit is known as a Pi-type antenna tuner. A Pi-network is a completely different circuit topology that relies on a specific arrangement of capacitors and an inductor (resembling the Greek letter Pi), rather than a matching transformer.
