Q

What class of amplifier is used as linear in order not to distort the modulation components?

🔍 Key Concepts

• Amplifier classes (A, B, C) and how they differ in conduction angle and linearity • Why linearity is important for amplitude/SSB modulation (to avoid distortion of the modulation envelope) • Trade‑off between efficiency and fidelity/linearity in RF power amplifiers

💭 Think About

• Which amplifier class conducts over the entire input cycle, and how does that affect distortion? • For an HF/SSB or AM transmitter’s RF power amplifier, what happens to the modulation waveform if the stage is not linear? • Which classes are commonly used for RF power versus audio/IF stages when preserving the shape of the waveform is critical?

✅ Before You Answer

• Identify which class has maximum linearity but lower efficiency • Verify which classes (B and C) are typically used for more efficient but less linear RF power stages with significant distortion unless special techniques are used • Confirm which class is specifically noted in radio theory texts as being used where undistorted modulation components must be preserved
