NTE805
Integrated Circuit
IF Gain Block for FM Receiver
Description:
The NTE805 provides function of an IF gain block and is designed for use in communications and FM
receivers. The device consists of a three−stage limiting amplifier operating from a regulated power
supply, and 330Ω input and output terminations with 7.0pF of shunt capacitance required for 10.7MHz
ceramic filters. The device also offers a 7.7 voltage regulated supply for external use from pin 6.
Features:
D Gain at 10.7MHz: 35dB Typ.
D Operating Voltage Range: 10V to 20V
D Excellent Temperature Stability
D Power Supply Rejection Ratio: 40dB Typ.
