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 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 -72 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 a 3 V lithium battery with typically 2.5 mA current. For system design flex-
ibility, the baseband output is accessible, and the comparator threshold can be changed externally between two settings. Typical appli-
cations include unlicensed wireless remote-controls, and digital data links operating in the USA under FCC Part 15.249 and in Canada
under DOC RSS-210.
