MER is a measure of signal to noise ratio at optimal eye sampling point.
Optimized PLL bandwidth settings vs. data rate defined in Table 31.
Measured as the maximum unmodulated power.
A combined single-ended PA and LNA match can reduce the maximum achievable output power by up to 1 dB.
This includes the second harmonic.

Test Conditions/Comments
Measured as per TELEC T-245 for T96
compliance, 950 MHz to 958 MHz band,
single-ended PA with combined output. For
spurious emissions compliance in the
1.8845 GHz to 1.9196 GHz frequency band,
a seventh-order PA harmonic filter is used.
This has an insertion loss of up to 1.5 dB.

PA Impedance in Rx mode
Load impedance between RFIO_1P and
RFIO_1N to ensure maximum output power
