Operating temperature range is as follows: –40 C to +85 C.
Datarates should be limited to adhere to edge of band requirements in accordance with ETSI 300-220

levels to >10 dBm at both 433 MHz and 868 MHz
Recommended PFD frequencies are 4.42368 MHz (22.1184/5) for 868 MHz, and 4 MHz for 433 MHz operation. Compliance for higher output powers will require
an external filter. See Applications section.
The output power is limited by the spurious requirements of ETSI at +55 C. The addition of an output filter (see Applications section) will allow increased output

These spurious levels are based on a maximum output power of +3 dBm for 868 MHz and +10 dBm for 433 MHz. It assumes a PFD frequency of <5 MHz.
Not production tested. Based on characterization.
