CC2400
7 RF Transmit section
Tc = 25°C, AVDD/DVDD1.8 = 1.8 V, DVDD3.3 = 3.3V (digital I/O) if nothing else stated. Measured on Chipcon’s
CC2400EM reference design.

±kHz The frequency corresponding to
the digital "0" is denoted f₀, while
f₁ corresponds to a digital "1".
The frequency deviation is given
by f_d=±(f₁−f₀)/2. The RF carrier
frequency, f_c, is then given by
f_c=(f₀+f₁)/2.
