HIGH-PERFORMANCE RECEIVERS, TRANSMITTERS,
AND TRANSCEIVERS FOR SUB-GHz ISM
With the largest portfolio of sub-GHz ISM wireless products available, our RF transmitters and receivers achieve
the best balance of high efficiency, high integration, high performance, low power consumption, and small package
sizes.
KEY FEATURES AND BENEFITS
BLOCK DIAGRAM
• Highest sensitivity receivers (as low as -115dBm
ASK, -110dBm FSK) and highest output power
transmitters (up to +16dBm) provide improved RF
performance
• Widest supply voltage ranges (2.1V to 5.5V) and full
automotive temperature ranges (-40°C to +125°C)
support many applications
• Lowest power consumption (~5.3mA Tx at +10dBm,
~5.2mA Rx) extends battery life
• Smallest packages (3mm x 3mm) and fully
integrated functions reduce external components
and total solution size
