Figure 1. Block diagram of the 2 GHz production test board used for NF, Gain, OIP3 , P1dB, PAE
and ACLR measurements. This circuit achieves a trade-off between optimal OIP3, P1dB and
VSWR. Circuit losses have been de-embedded from actual measurements.
Product Consistency Distribution Charts
Notes:
1. Distribution data sample size is 500 samples taken from 5 different wafers. Future wafers allocated
2. Measurements are made on production test board, which represents a trade-off between optimal
to this product may have nominal values anywhere between the upper and lower limits.
