3845 AM NOISE BLANKER This noise blanker integrated circuit contains all of the necessary circuitry for adding an extremely efficient (patented) noise-blanking technique to any type of AM tuner or receiver with RF input frequencies (or a first IF) to 30 MHz. The A3845ELW and A3845SLW feature dual audio channels and are intended for AM-stereo or independent sideband applications. A high input impedance, high-gain, broadband RF amplifier permits these devices to be directly connected to the RF st
