Footprint
This amplifier-sequenced hybrid (ASH) receiver is based on several leading-edge
technologies that allow outstanding performance in a small and simple-to-apply
module. Two surface-accoustic-wave (SAW) devices are employed. Front-end fil-
tering by a low-loss coupled-resonator SAW filter provides excellent selectivity.
Typical sensitivity better than -100 dBm is achieved with no RF oscillating or regen-
erative circuits. This results in virtually no RF spurious emissions. A low-loss SAW delay line provides the time delay necessary to
sequence the two RF amplifiers. Time sequencing of the RF gain eliminates the need for frequency conversion prior to AM detection.
This receiver is designed to operate from 3 V lithium battery with typically1.1 mA current. For system design flexibility, the baseband
output is accessible, and the comparator threshold can be changed externally between two settings. Typical applications include unli-
censed wireless remote-controls, security and data-link devices operating in the USA under FCC part 15, in Australia, in Japan, and in
Korea.
