🔍 Key Concepts

• Purpose of an RF (radio frequency) amplifier stage in a receiver or transmitter chain • What extra components and design concerns RF stages introduce compared with simple audio stages • Practical installation issues with RF circuitry, such as interference and stability

💭 Think About

• For each option, ask: is this really a disadvantage that comes specifically from adding an RF amplification stage? • Think about what an RF amplifier actually handles (RF signals) versus what a loudspeaker needs (audio power) — are these directly related? • Consider whether extra tuning components and shielding are commonly needed when working with RF stages and why that might be.

✅ Before You Answer

• Identify which choices describe added complexity or hardware that comes with RF amplification stages • Decide whether loudspeaker operation is directly determined by the RF stage or by later audio stages • Check if interference, oscillation, and unwanted radiation are common problems that shielding and extra tuning help to control in RF circuits
