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.

Thereceiveroffersanexceptionallyhighlevelofintegration

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

receiversystemstobeimplementedwithlessthan1mAsupply,

and a wide IF bandwidth and drive stage to interface to an

externalceramicIFbandpassfilteratintermediatefrequencies

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
