Notes:
1. Operation of this device in excess of any one of these parameters may cause permanent damage.
2. Assumes DC quiescent conditions.
3. Board (package belly) temperatureT
B
is 25°C. Derate 22 mW/°C for T
B
> 83°C.
4. Channel to board thermal resistance measured using 150°C Liquid Crystal Measurement method.
5. Device can safely handle +27dBm RF Input Power provided IGS is limited to 46mA. IGS at P1dB drive level is bias circuit dependent.

Notes:
5. Distribution data sample size is 500 samples taken from 5 different wafers. Future wafers allocated to this product may have nominal values
anywhere between the upper and lower limits.
6. 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.
