← ScienceWhich outcome results when impedance mismatch exists between cascaded microwave filter stages?
A)Increased insertion loss occurs easily✓
B)Improved filter group delay appears
C)Reduced spurious signal generation comes
D)Enhanced overall power handling arrives
💡 Explanation
Increased insertion loss occurs because the **multiple reflections** mechanism causes a portion of the signal to be reflected back at each interface, therefore the received signal is attenuated, rather than being efficiently passed through like a matched system.
