Features

of low supply voltage, in-band interference rejection (anti-jamming detector), a 2 stage power down to enable receiver systems to be implemented with less than 1mA supply, and a wide IF bandwidth and drive stage to interface to an external ceramic IF band pass filter at intermediate frequencies from 0.2MHz to 15MHz. The KESRX04 is an ideal receiver for difficult reception areas where high level interferers would jam the wanted signal. The anti-jamming circuit allows operation to be possible with.
