Stress beyond those listed under absolute maximum ratings may cause permanent damage to the XE1218

device. These are stress ratings only, and functional operation of the device at these or any other condition

beyond those under “recommended operating conditions” is not implied. Exposure to “absolute maximum

ratings” conditions for extended periods may affect the device reliability.

3.2 Recommended operating conditions and electrical specifications

General conditions: Temp = 25°C, VDD= 1.3V, Carrier Frequency=160MHz, unless otherwise specified
