What primarily affects the performance of microwave transmission lines when not properly handled?

Receiver interference is a significant concern in microwave transmission lines when they are not handled properly. This kind of interference can disrupt the quality of the received signal, leading to degradation of the communication link. Poor handling can cause unwanted coupling of signals from nearby sources, electromagnetic interference, or even reflections and losses due to improperly connected or damaged transmission lines. All of these issues can ultimately lead to a receiver that is unable to process the incoming signal accurately, which is critical in microwave communications where precise signal quality is essential for effective data transmission.

While bandwidth capabilities and power handling are also important factors that can be affected by improper management of microwave transmission systems, the direct impact on the receiver's ability to function optimally is more closely tied to interference issues. Therefore, understanding how to maintain the integrity of the transmission lines and avoid external disruptions is crucial in ensuring reliable microwave communication.
