Data Sheet

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:
RF Amplifier
Frequency Counter
IF Amplifier
Detector
AGC
Signal Meter Driving

Features:
RF Amplifier Stage:
Good quieting sensitivity by means of low noise transistors and cascade connecting.
Frequency Converter Stage:
Splendid spurious characteristics by means of reduction of high frequency distortion in local
oscillation and differential mixer.
IF Amplifier Stage:
Reasonable distortion by wide output dynamic range.
Detector Stage:
Low distortion even at deep modulation considering diagonal clip or negative clip.
AGC Stage:
Wide AGC range and good large input signal characteristics by AGC’d IF and RF amplifier
stage.
Signal Meter Driving Stage:
Excellent linearity to input signal.
Others:
Stabilized biasing against supply voltage drifting over all stages. Particularly superior compensation
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.
