FM IF Amp

Description:

The NTE736 is a high performance monolithic FM Gain Block using the planar epitaxial process. The

FM gain block consist of a three stage direct coupled amplifier with 330Ω input and output termina-

tions and the 7pF shunting capacitance required for a 10.7MHz FM IF strip utilizing commercially

available ceramic filters. Included on the chip is a 7.8V active regulator providing up to 10mA of current

to an external load such as an FM tuner.

The NTE736 features full temperature compensation for the IF amplifier and the 7.8V regulator. Excel-

lent power supply rejection eliminates the need for an external regulated supply. An output from the

second stage of the IF amplifier provides a means of external gain control without affecting the input

or output terminations. The device is packaged in a 8−lead mini DIP.
