NTE1301
Integrated Circuit
AM/FM IF
Description:
The NTE1301 is a silicon monolithic integrated circuit in a 7–Lead SIP type package designed for the
AM/FM IF amplifier of a radio receiver. Two differential amplifiers and an AGC circuit perform good
limiting quality for FM operation and good AGC characteristics for AM operation.
