Transmit
Table 2-9 lists the key parameters of the integrated IEEE 802.15.4-2003 transmitter on the EM35x.
Note: Transmit measurements were collected with Ember’s EM35x Ceramic Balun Reference Design (Version
A0) at 2440 MHz. 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. In
terms of impedance, this reference design presents a 3n3 inductor in parallel with a 100:50 Ω balun to the RF
pins.
