🔍 Key Concepts

• Behavior and purpose of RF isolators and how they protect transmitters from reflected power • What a circulator does in RF systems and how many ports it typically has • General purpose of wave traps and multiplexers in communication systems

💭 Think About

• Which device’s main job is specifically to let RF power pass almost freely in one direction but block or absorb power coming back in the opposite direction? • Think about which component is commonly placed between a transmitter and an antenna to protect the transmitter from antenna mismatch or reflected power. • Which option is more associated with routing or combining signals, rather than strictly one‑way protection from reverse RF energy?

✅ Before You Answer

• Verify which device is described as non‑reciprocal (different behavior depending on direction of travel). • Check which option is commonly used as transmitter protection in marine and other RF systems. • Confirm which components (among the choices) are primarily for filtering or frequency separation rather than directional RF protection.
