🔍 Key Concepts

• Role of the first IF amplifier in a superheterodyne receiver • Meaning of noise figure and why early stages are critical • Difference between selectivity and sensitivity in receivers

💭 Think About

• Ask yourself: which receiver stage has the greatest impact on overall noise performance and weak-signal reception? • Consider what part of the receiver usually handles filtering for selectivity – is it the IF amplifier itself or associated filter networks? • Think about why designers place a high-gain, low-noise amplifier right after the mixer rather than later in the IF chain.

✅ Before You Answer

• Verify which parameter of a receiver is most affected by the first active stages following the antenna and mixer. • Confirm whether selectivity is primarily a function of filters (like crystal/ceramic filters) or the gain device itself. • Check standard radio theory references on how overall receiver noise figure is dominated by the first stages (RF amp / first IF amp).
