3.6.2
Table 8 lists the key parameters of the integrated IEEE 802.15.4 transmitter on the EM260.
Note: Transmit Measurements were collected with Ember’s EM260 Ceramic Balun Reference Design at
2440MHz and using the EmberZNet software stack Version 3.0.1. The Typical number indicates one standard
deviation below the mean, measured at room temperature (25C). The Min and Max numbers are measured
over process corners at room temperature (25C).
