433.92 MHz ASH Receiver
• Ideal for 433.92 MHz, 3 V Receivers in Europe (I-ETS 300 220)
• High-Sensitivity Passive Design with No RF Oscillation
• Baseband Data Rate of 20 kbps
• 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
SM-10 Case
technologies that allow outstanding performance in a small and simple-to-apply mod-
ule. 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 emis-
sions. 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 1.3 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, security and data-link devices oper-
ating in Europe under ETSI I-ETS 300 220.

The RX Series SMT Hybrid ASH Receivers
CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.
Notes:
1. Unless noted otherwise, specifications apply over the entire specified operating temperature and voltage ranges.
2. One or more of the following United States patents apply: 4,454,488; 4,616,197; 4,749,964; 4,902,925. Other patents are pending.
3. Typically, equipment utilizing this device requires emissions testing and government approval, which is the responsibility of the
equipment manufacturer.
4. The design, manufacturing process, and specifications of this device are subject to change without notice.
5. A variety of on-off-keyed (OOK) pulse modulation schemes are possible since digital decoding is an external function (not included
in the ASH receiver).
6. These parameters apply over the absolute minimum operating passband which is referenced to fC.
7. With interfering signal matched to the receiver modulation and code. See “Typical Modulated Interference Rejection” for a more
detailed view.
8. Sample repetition rates greater than 1 MHz are available in custom versions. Contact RFM for details.
9. Baseband data rates are available to 20 kbps, respectively, in custom versions. Contact RFM for details. See HX/RX Designer’s
Guide for details on data rate limits.
10. The default comparator threshold (with terminal 5 not connected) is optimized for low duty-cycle, or “bursty” data and eliminates
noise output when there is no RF signal. The override threshold (with terminal 5 connected to ground) is optimized for continuous
data.
11. The ASH receiver is designed to drive a single CMOS load.
