●Description
●The CC11x1-Q1 device family is designed for very low-power wireless applications. The circuits are mainly intended for the Industrial, Scientific and Medical (ISM) and Short Range Device (SRD) frequency bands at 315 MHz, 433 MHz, 868 MHz, and 915 MHz, but can easily be programmed for operation at other frequencies in the 310-MHz to 348-MHz, 420-MHz to 450-MHz, and 779-MHz to 928-MHz bands.
●Features
●• Qualification in Accordance With AEC-Q100 Grade 1
●• Extended Temperature Range Up To 125°C
●• Radio-Frequency (RF) Performance
●– High Sensitivity (–114 dBm at 1.2 kBaud, 315 MHz, 1% Packet Error Rate)
●– Low Current Consumption (15.5 mA in Receive, 1.2 kBaud, 315 MHz)
●• Programmable Output Power up to +10 dBm for All Supported Frequencies
●• Excellent Receiver Selectivity and Blocking Performance
●• Programmable Data Rate From 1.2 kBaud to 250 kBaud
