This amplifier-sequenced hybrid (ASH) receiver is based on several leading-edge
technologies that allow outstanding performance in a small and simple-to-apply mod-
ule. Two surface-accoustic-wave (SAW) devices are employed. Front-end filtering
by a low-loss coupled-resonator SAW filter provides excellent selectivity. Typical
sensitivity better than -100 dBm is achieved with no RF oscillating or regenerative 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 typically 1.1 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 unlicensed wireless remote-controls, security and data-link
devices operating in Europe under ETSI I-ETS 300 220.
