RX1300

This amplifier-sequenced hybrid (ASH) receiver RX1300 is based on several leading-edge echnologies that allow outstanding performance in a small and simple-to-apply odule. Two surface-accoustic-wave (SAW) devices are employed. Front-end filtering y a low-loss coupled-resonator SAW filter provides excellent selectivity. ypical sensitivity better than -100 dBm is achieved with no RF oscillating or regenerative circuits. This results in virtually no RF spurious missions. A low-loss SAW delay line provides the time delay necessary to sequence the two RF amplifiers. Time sequencing of he RF gain eliminates the need for frequency conversion prior to AM detection. This receiver RX1300 is designed to operate from a 3 V lithium attery with typically 1.1 mA current. For system design flexibility, the baseband output is accessible, and the comparator threshold can e changed externally between two settings. Typical applications include unlicensed wireless remote-controls, security and data-transmission evices operating in the United Kingdom under DTI MPT 1340 and in the USA under FCC Part 15.
