Which 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.
