What element in a splitter and directional coupler serves to determine the voltage sent to the ports?

1. Plug-in fuses

2. Analog signal processors

3. Intrusive test points

4. Voltage dividers

The correct answer is: Plug-in fuses

In a splitter and directional coupler, the element responsible for determining the voltage sent to the ports is the voltage divider. A voltage divider is a configuration that takes a single voltage input and divides it into smaller output voltages, based on the resistance values involved. This is crucial for ensuring the correct signal level is sent to each port without overloading the equipment or causing signal distortion. Voltage dividers are often used in RF applications, such as splitters and couplers, to maintain appropriate signal levels and match impedance, which is essential for effective power distribution among multiple outputs. Unlike plug-in fuses, which are intended to protect circuits from overcurrent, or analog signal processors, which handle signal conditioning and manipulation, the voltage divider specifically focuses on controlling voltage levels at the ports. Intrusive test points are used for measuring signals but do not directly influence how voltage is distributed to the ports. Therefore, in the context of the question, the voltage divider is the correct answer.
