14.9 RF electrical characteristics
14.9.1 Receive
Note:
Table 152 lists the key parameters of the integrated IEEE 802.15.4 receiver on the
STM32W.
Receive 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
