NTE1495
Integrated Circuit
AM RF Mixer, IF Amplifier
Description:
The NTE1495 is a monolithic integrated circuit in a 15−Lead Staggered SIP type package. This device
is suitable for use as an AM tuner in automotive radio receivers, specifically where compact mounting
is required and contains an RF amplifier, mixer, IF amplifier, and two types of AGC circuits.
Features:
D High Sensitivity
D Excellent Two−Signal Selectivity Characteristics which Permits Receiving any Weak Signal
Without Interference from the Next Strongest Signal
D Wide AGC Range Provided by Two AGC Circuits (Delay Type) Employed in the IF and RF
Stages, in Addition to the Ability to Withstand Large Input and to the Yeild of High S/N Ratio
