Multiple choice general knowledge

What is one reason to use an impedance matching transformer?

  1. To minimize SWR in the transmission line

  2. To reduce power dissipation in the transmitter

  3. To minimize SWR at the antenna

  4. To maximize the transfer of power

D Correct answer
Explanation

Impedance matching transformers maximize power transfer between circuits with different impedance levels. While they can affect SWR, their primary purpose is optimizing power efficiency rather than minimizing standing waves.
