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.

Notes:
1. Distribution data sample size is 500 samples
taken from 3 different wafers. Future wafers
allocated to this product may have nominal
values anywhere between the upper and
lower limits.
2. Measurements are made on production test
board, which represents a trade-off between
optimal OIP3, P1dB and VSWR. Circuit losses
have been de-embedded from actual
measurements.
