KESRX04 260 to 470MHz. ASK Receiver with Power Down Preliminary Information DS4997 - 1.5 August 1998 The KESRX04 is a single chip ASK (Amplitude Shift Key) Receiver IC. It is designed to operate in a variety of low power radio applications including keyless entry, general domestic and industrial remote control, RF tagging and local paging systems. The receiver offers an exceptionally high level of integration and performance to meet the local oscillator radiation requirements of regulatory auth.

KESRX04 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
