Question 1
What is the main purpose of RF-LO isolation?
- To measure output power
- To prevent RF interference with the LO
- To measure signal gain
💡 Hint: Think about what can happen if these signals interact.
Question 2
True or False: RF-IF isolation ensures that RF signals can easily contaminate the IF output.
- True
- False
💡 Hint: Remember the function of isolation.

Challenge Problems
Push your limits with challenges.
Question 1
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.
Question 2
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?
