2.7. RF Electrical Characteristics

2.7.1. Receive

Table 2.8 lists the key parameters of the integrated IEEE 802.15.4-2003 receiver on the EM342.

Receive measurements were collected with the Silicon Labs EM357 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.
