NTE734 Integrated Circuit TV FM IF Gain Block Description: The NTE734 F−M gain block linear monolithic integrated circuit is designed for use in communicatios and high fidelity f−m receivers. This device consists of a three−stage limiting amplifier section, a regulated powersupply, an a−m detector and 330 ohm input and output terminations with 7pF shunting capacitance required foer 10.7MHz ceramic filters. Gain can be adjusted without effect on input and output conditions by addition of a fixed resistor between pins 3 and 7.
