Ideal for 868.35 MHz, 3 V Data Receivers in Europe  
High-Sensitivity Passive Design with No RF Oscillation  
Use with HX4007 for 2.4 kbps Data Rate  
Simple to Apply with External Parts Count  
Rugged, Surface-Mount Package with 130 mm2 Footprint  
SM-10 Case  
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 fil-  
tering by a low-loss coupled-resonator SAW filter provides excellent selectivity. Typ-  
ical 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 a 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 operat-  
ing in Europe under the European Telecommunication Standard (ETSI) 300-220-1.
