  • Page 5: Functional Description

    Philips Semiconductors IF amplifier/demodulator for FM radio receivers FUNCTIONAL DESCRIPTION Limiter-amplifier This has five stages of IF amplification using balanced differential limiter-amplifiers with emitter--follower coupling. Decoupling of the stages from the voltage supply lines and an internal high-ohmic DC feed-back loop give a very stable IF performance.

  • Page 21 Philips Semiconductors IF amplifier/demodulator for FM radio receivers SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities.
