Notes:
4. P1dB measurements were performed with
passive biasing in Production Test Circuit
(Figure 4.). Quiescent drain current, Idsq, is
set by a fixed Vref with no RF drive applied.
As P1dB is approached, the drain current
may increase or decrease depending on
frequency and DC bias point which typically
results in higher P1dB than if the drain
current is maintained constant by active
biasing.
5. P1dB measurements were performed in
Evaluation Test Circuit with source resistor
biasing which maintains the drain current
near the quiescent value under large signal
conditions.
