🔍 Key Concepts

• Typical forward current range for small signal silicon diodes • How much current a RADAR mixer/detector diode normally handles (microamp to low milliamp region) • Impact of too much current on noise, sensitivity, and diode life

💭 Think About

• In a sensitive mixer/detector stage, do you expect the diode to run at power-transistor currents, or very small signal currents? • Which of these current values would most likely overheat or heavily bias a tiny crystal diode, changing its characteristics? • Think about typical current ratings for small signal RF diodes used in receivers—are they closer to a few mA or tens/hundreds of mA?

✅ Before You Answer

• Eliminate values that look more like power device currents rather than small RF detector currents • Consider that mixer/detector diodes are designed for low noise and high sensitivity, not power handling • Ask: which value would keep the junction cool and linear in a delicate RADAR receiver front end?
