Challenge Problems
Push your limits with challenges.
Question 1
Design an RF amplifier that needs to amplify a signal by a gain of 50 over a bandwidth of 10 MHz while ensuring a noise figure of less than 3 dB. List the components and method used.
💡 Hint: Consider how each component interacts with frequency and amplification.
Question 2
Explain the trade-offs of increasing signal gain at the expense of linearity in an RF amplifier. How would this decision affect the amplifier’s application?
💡 Hint: Feedback mechanisms can help maintain linearity while adjusting gain.
