🔍 Key Concepts

• Even-order vs odd-order harmonics in RF power amplifiers • How symmetry in amplifier stages affects cancellation of certain harmonics • Differences between push-pull, push-push, and single-ended amplifier configurations

💭 Think About

• Which amplifier configuration uses two devices operating on opposite halves of the waveform so that certain harmonics cancel out? • How does waveform symmetry around the zero axis influence the presence of even-order harmonics? • Between the listed amplifier classes and configurations, which is specifically known for harmonic cancellation by symmetry rather than just efficiency or biasing?

✅ Before You Answer

• Identify which choice represents a balanced / symmetric configuration using two active devices handling opposite signal phases. • Check which options are biasing classes (A, AB, C) versus specific circuit topologies. • Confirm which topology is typically used in RF design when you want to cancel even-order harmonics in the output transformer or combiner.
