Transmit

Table 68 lists the key parameters of the integrated IEEE 802.15.4 transmitter on the

STM32W.

Note:

Transmit measurements were collected with ST’s STM32W Ceramic Balun Reference

Design (Version A0) at 2440 MHz. The Typical number indicates one standard deviation

above the mean, measured at room temperature (25

° C). The Min and Max numbers were

measured over process corners at room temperature
