Quick quizzes to reinforce your learning

Question 1

What is the formula for quality factor in L-section networks?

Q = R_high/R_low
Q = √(R_high/R_low - 1)
Q = R_low/R_high

💡 Hint: Focus on how quality is derived from resistance values.

Question 2

True or False: The stub length decreases with increasing susceptibility.

True
False

💡 Hint: Think about the relationship between length and reactance.

Challenge 1 Hard

If a designer needs to calculate the quality factor for an RF amplifier with R_high=150Ω and R_low=75Ω, what steps do they take and what is the resulting Q?

💡 Hint: Focus on simplifying the resistance ratio before applying the square root.

Challenge 2 Hard

A matching network uses a stub length where B=0.6 S and Y0=0.9 S with λ=0.4 m. Calculate the stub length and discuss the implications of variations in reactance.

💡 Hint: Visualize the stub impacts of lower vs higher reactance adjustments.
