🔍 Key Concepts

• Power detector function in radio/electronics (what quantity does it measure?) • Difference between square-law detection and linear detection in terms of input vs. output relationship • How some detector circuits behave at low input levels versus higher input levels

💭 Think About

• Think about how a power detector’s output should relate to the RF input signal: is power proportional to the signal amplitude or to the square of the amplitude? • Recall that many diode detector circuits change their behavior depending on the signal strength range—how does this affect whether they appear square-law or linear? • Consider whether practical detector circuits are restricted to only one mode of operation or if they can operate in more than one region depending on conditions.

✅ Before You Answer

• Make sure you understand that power is proportional to the square of voltage or current in many RF contexts • Check how a diode detector characteristic curve looks at small vs. large signal levels • Verify whether the exam’s use of "power detector" refers to a device that can operate in different regions (square-law and linear) depending on signal level.
