Electrical characteristics
13.6.2
Transmit
Table 17 lists the key parameters of the integrated IEEE 802.15.4 transmitter on the SN260.
Note:
Transmit measurements were collected with Ember’s SN260 Lattice Balun Reference
Design at 2440 MHz and using the EmberZNet software stack Version 3.0.1. The Typical
number indicates one standard deviation above the mean, measured at room temperature
(25° C). The Min and Max numbers are measured over process corners at room
temperature (25° C).
