The electrical specifications are given with the following conditions unless otherwise specified:

• VBAT_IO = VBAT = 3.3 V, all current consumptions are given for VBAT connected to VBAT_IO
• Temperature = 25 °C
• FXOSC = 32 MHz, with specified crystal
• FRF = 434/490/868/915 MHz
• All RF impedances matched
• Transmit mode output power defined into a 50 load impedance
• FSK BER = 0.1%, 2-level FSK modulation without pre-filtering, BR = 4.8 kb/s, FDA = ± 5 kHz, BW_F = 20 kHz double-sided
• LoRa® PER = 1%, packet 64 bytes, preamble 8 symbols, CR = 4/5, CRC on payload enabled, explicit header mode
• RX/TX specifications given using default RX gain step and direct tie connection between Rx and Tx
• Blocking immunity, ACR and co-channel rejection are given for a single tone (CW) interferer and referenced to sensitivity +3 dB
• Optional TCXO and RF Switch power consumption always excluded

Throughout this document, all receiver bandwidths are expressed as 'double-sideband'. This is valid for LoRa® and FSK modulations.

Stresses above the values listed below may cause permanent device failure. Exposure to absolute maximum ratings for extended periods may affect device reliability, reducing product life time.
