RF Electrical Characteristics

Receive
Table 7 lists the key parameters of the integrated IEEE 802.15.4 receiver on the EM260.
Note: Receive Measurements were collected with the Silicon Labs EM260 Ceramic Balun Reference Design at
2440MHz and using the EmberZNet software stack Version 3.0.1. The Typical number indicates one standard
deviation above the mean, measured at room temperature (25C). The Min and Max numbers are measured
over process corners at room temperature (25C).
Note: The adjacent channel rejection (ACR) measurements were performed by using an unfiltered, ideal IEEE
802.15.4 signal of continuous pseudo-random data as the interferer. For more information on ACR
measurement techniques, see document AN709, Adjacent Channel Rejection Measurements.
