Footprint
This amplifier-sequenced hybrid (ASH) receiver is based on several leading-edge technologies that allow out-
standing performance in a small and simple-to-apply module. 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 -92 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 se-
quence 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 1.3 mA cur-
rent. 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 the USA under FCC Part 15, in Australia, in Japan, and in Korea.
