Electrical Specifications
4.1.10.7 Sub-GHz RF Transmitter characteristics for 433 MHz Band
Unless otherwise indicated, typical conditions are: T = 25 °C, VREGVDD = AVDD = IOVDD = 3.3 V, DVDD = RFVDD = PAVDD.
RFVDD and PAVDD path is filtered using ferrites. Crystal frequency=38.4 MHz. RF center frequency 433 MHz.
