RFM92W/93W V3.0
2.5. Chip Specification
The tables below give the electrical specifications of the transceiver under the following conditions: Supply voltage
VBAT1 = VBAT2 = VDD = 3.3 V, temperature = 25 °C, FXOSC = 32 MHz, F_RF = 915 MHz, Pout = +13 dBm,
2 level FSK modulation without pre-filtering, FDA = 5 kHz, Bit Rate = 4.8 kbps and terminated in a matched 50 Ohm
impedance, unless otherwise specified. Shared Rx and Tx path matching.
Note Unless otherwise specified, the performance in the 868 MHz band is identical or better.
