Challenge Problems
Push your limits with advanced challenges
A radio receiver is designed to receive signals at an RF frequency of 1500 MHz. If the mixer uses a Local Oscillator frequency of 1400 MHz, what is the resulting Intermediate Frequency?
💡 Hint: Use the difference between RF and LO to find the IF.
If a mixer produces intermodulation products at frequencies that interfere with the desired signal, what strategies can be implemented to mitigate this issue?
💡 Hint: Think about design and filtering solutions.
