Table 8 lists the key parameters of the integrated IEEE 802.15.4 transmitter on the EM250.
Note: Transmit Measurements were collected with Ember’s EM250 Lattice Balun Reference Design (Version
Transmit
B1) 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 (25°C). The Min and Max
numbers were measured over process corners at room temperature.
