1.1. Definition of Test Conditions

Production Test Conditions:



TA =+25 °C



VDD =+3.3VDC



Sensitivity measured at 434 MHz using a PN15 modulated input signal and with packet handler mode

enabled.



External reference signal (XIN) = 1.0 VPP at 30 MHz, centered around 0.8 VDC



RF input and output levels can typically be achieved at the antenna port after filtering components.

Qualification Test Conditions:



TA = –40 to +85 °C (typical = 25 °C)



VDD = +1.8 to +3.6 VDC (typical = 3.3 VDC)



Use TX/RX Split Antenna reference design or production test schematic



RF input and output levels can typically be achieved at the antenna port after filtering components.
