🔍 Key Concepts

• Use the decibel (dB) formula for voltage gain: gain (dB) = 20 × log10(Vout/Vin) • First compute the voltage ratio between output and input • Understand typical gain ranges for high-gain IF amplifiers in RADAR receivers (usually tens to low hundreds of dB, not thousands)

💭 Think About

• What is the ratio of the output voltage (2 V) to the input voltage (2 microvolts)? Write it as a pure number before doing any dB math. • For voltage (not power) gain, do you use 10 × log10(...) or 20 × log10(...)? Why? • Once you find the dB value, which of the answer choices is closest to your calculated gain?

✅ Before You Answer

• Be sure you convert microvolts to volts correctly before forming the ratio. • Confirm you are using 20 × log10(Vout/Vin) (for voltage) rather than the power formula. • After calculating, check whether the result is in a realistic range for amplifier gain (tens to a few hundred dB, not extreme values).
