🔍 Key Concepts
• Diode detector characteristic curve between voltage and current
• Difference between square-law region and linear region of a diode
• Behavior of a diode detector at weak vs. strong RF signal levels
💭 Think About
• On the diode I‑V curve, what happens at very low input voltages versus higher input voltages?
• In which region (square-law or linear) does the detected output voltage become roughly proportional to the square of the input RF voltage?
• For large RF signals, does the detector output tend to be more nearly proportional to the input amplitude or the square of the input amplitude?
✅ Before You Answer
• Be clear which signal level (weak or strong) corresponds to the square-law region of operation
• Be clear which signal level (weak or strong) corresponds to the linear region of operation
• Check whether any choice correctly combines both statements about weak and strong signal behavior of a diode detector
