Electrical Specifications
4.17.9 EZRadio (R55) Transmitter AC Electrical Characteristics
The maximum data rate is dependent on the XTAL frequency and is calculated as per the formula: Maximum Symbol Rate = Fxtal/60,
where Fxtal is the XTAL frequency (typically 30 MHz).
Conducted measurements based on RF evaluation board. Output power and emissions specifications are dependent on transmit fre-
quency, matching components, and board layout.
