MGA-71543 Typical Performance, continued
T_c = 25°C, Z_o = 50, V_d = 3V, I_d = 10 mA unless stated otherwise. Data vs. frequency was measured in Figure 5 test system
and was optimized for each frequency with external tuners.

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.
