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 of -83 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 elimi-
nates the need for frequency conversion prior to AM detection. This receiver is designed to operate from a 3 V lithium battery with typ-
ically 2.5 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 and digital data links operating in the
USA under FCC Part 15.249 and in Canada under DOC RSS-210.
