Question 235

What is the result of increasing the Q of an impedance-matching circuit?

  1. Matching bandwidth is decreasedBonne réponse
  2. Matching bandwidth is increased
  3. Losses increase
  4. Harmonics increase

Explication

Q and bandwidth are inversely related, so a higher-Q matching network passes a narrower band of frequencies around the design point. A high-Q match is more selective and must be retuned more often as frequency changes.
