RX1320

This amplifier-sequenced hybrid (ASH) receiver RX1320 is based on several leading-edge echnologies that allow outstanding performance in a small and simple-to-apply module. wo surface-accoustic-wave (SAW) devices are employed. Front-end filtering y a low-loss coupled-resonator SAW filter provides excellent selectivity. Typical ensitivity 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 sequence the two RF amplifiers. Time sequencing of the RF ain eliminates the need for frequency conversion prior to AM detection. This receiver RX1320 is designed to operate from a 3 V lithium battery ith typically 1.3 mA current. For system design flexibility, the baseband output is accessible, and the comparator threshold can be hanged externally between two settings. Typical applications of RX1320 include unlicensed wireless remote-controls, security and data-transmission evices operating in United Kingdom under DTI MPT 1340 and in the USA under FCC part 15.
