DATASHEET
2.5. Chip Specification
The tables below give the electrical specifications of the transceiver under the following conditions: Supply voltage
VDD=3.3 V, temperature = 25 °C, FXOSC = 32 MHz, FRF = 169/434/868/915 MHz (see specific indication), Pout =
+13dBm, 2-level FSK modulation without pre-filtering, FDA = 5 kHz, Bit Rate = 4.8 kb/s and terminated in a matched 50
Ohm impedance, shared Rx and Tx path matching, unless otherwise specified.
Note Specification whose symbol is appended with “_LF” corresponds to the performance in Band 2 and/or Band 3, as
described in section 5.3.3. “_HF” refers to the upper Band 1
