Challenge Problems
Push your limits with advanced challenges
Given an RF signal of +15 dBm and a local oscillator of +10 dBm, calculate the LO-IF isolation if the measured IF output is +5 dBm.
💡 Hint: Remember the isolation formula involving output and input powers.
Discuss the potential consequences for an RF receiver if the RF-IF isolation is measured at only 10 dB instead of the ideal 25 dB.
💡 Hint: What does low isolation imply for unsuspected signals?
