← ScienceWhich consequence results when imperfect impedance matching occurs transmitting microwaves through coaxial cables?
A)Increased reflected power wave propagation✓
B)Decrease conductor temperature dielectric breakdown
C)Enhanced signal amplification gain bandwidth
D)Improved characteristic impedance length cable
💡 Explanation
Reflections increase because impedance mismatch disrupts optimal "wave propagation", driving energy back to the source rather than being transmitted forward. Therefore, reflected power rises, rather than alternative effects like dielectric breakdown, contingent to voltage levels.
