ECG744, RF/IF Amplifier IC for AM Radio Receiver Subsystems ~ (NTE744, SK3171)

Philips ECG ECG744, RF/IF Amplifier IC for AM Radio Receiver Subsystems ~ 14 Pin DIP (NTE744, SK3171, GEIC-24)

FEATURES:

• ECG744, RF/IF Amplifier IC for AM Radio Receiver Subsystems
• Low-noise, low-Rb, rf stage in cascode connection-eliminates Miller-Effect regeneration and allows controlled power rise by the choice of external components
• Mixer-oscillator stage with internal feedbackeliminates need for tapped or multi-winding oscillator coils
• Cascode If amplifier with controlled output impedance and negligible Miller Effect eliminatesregeneration and selectivity skewing
• Frequency-counter AGC circuit allows control of AGC response by selection of the couplingcapacitor
• Integral regulation with built-in surge protection
• Separately accessible amplifiers
• Package/Case: 14 Pin DIP
• Replaces: NTE744, SK3171, GEIC-24
