RX2010-121198

• Ideal for 916.5 MHz, 3 V Data Receivers in the USA and Canada 

• High-Sensitivity Passive Design with No RF Oscillation 

• Baseband Data Rate of 10 kb/s 

• Simple to Apply with External Parts Count 

• Rugged, Surface-Mount Package with 130 mm2 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 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 -80 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 3 V lithium battery with typically 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.
