The graph below shows operating load line and I-V characteristic of a Schottky diode at two different RF power levels. Under this bias condition RF resistance of the diode:
- A. Remains constant with the RF power level
- B. Decreases with the increase of RF power level
- C. Increases with the increase of RF power level
- D. None of the above
Answer: C. Increases with the increase of RF power level
Explanation: From the graph, as change of voltage for change in current from maximum to minimum value is large for large power. Hence resistance increases with increase of RF power level.
