Challenge Problems
Push your limits with challenges.
Question 1
Design a simple mixer-first receiver circuit using available components. Consider how the removal of the LNA might impact the receiver's gain.
💡 Hint: Identify what gain loss means without the LNA, and how to compensate with mixer design.
Question 2
Given that a mixer-first receiver achieves a linearity of 65 dB, calculate the potential reduction in noise figure compared to a standard configuration with an LNA providing 3 dB.
💡 Hint: Consider how noise figures relate and improve through system design innovations.
