NTE1214
Integrated Circuit
AM Tuner System
Description:
The NTE1214 is a high integrated circuit in a 16–Lead DIP type package designed for use in the AM
system of high grade receivers. This device contains most of the functions needed for AM receiving.
Functions:
D RF Amplifier
D Frequency Counter
D IF Amplifier
D Detector
D AGC
D Signal Meter Driving
Features:
D RF Amplifier Stage:
Good quieting sensitivity by means of low noise transistors and cascade connecting.
D Frequency Converter Stage:
Splendid spurious characteristics by means of reduction of high frequency distortion in local
oscillation and differential mixer.
D IF Amplifier Stage:
Reasonable distortion by wide output dynamic range.
D Detector Stage:
Low distortion even at deep modulation considering diagonal clip or negative clip.
D AGC Stage:
Wide AGC range and good large input signal characteristics by AGC’d IF and RF amplifier
stage.
D Signal Meter Driving Stage:
Excellent linearity to input signal.
D Others:
Stabilized biasing against supply voltage drifting over all stages. Particularly superior com-
pensation circuit in IF amplifier. Less deterioration of gain, detector output, and distortion in
low supply voltage range in order to get wide supply voltage range (7V* to 16V).
* Needs to vary peripheral parts and its value of RF and local oscillator stage for the purpose of low
supply voltage operation.
