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 require-
ments of regulatory authorities world-wide. Functionally the
device works in the same way as the KESRX01 with the added
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
interfering signals which are more than 14dB stronger than the
wanted signal, without the cost penalties of increased IF
selectivity and frequency accuracy.
