NTE703
Linear Integrated Circuit
RF−IF Amplifier
Description:
The NTE703 is an RF−IF amplifier intended for use as a limiting or non−limiting amplifier, harmonic
mixer, or oscillator to 150MHz. The low internal feedback of the device insures a higher stability−limited gain.
Features:
D Few external components
