Figure 21. Swept Power Tuned for Power at 2 GHz,
VDS = 4 V, IDSQ = 60 mA.
Notes:
1. P1dB measurements are performed with passive biasing. Quicescent drain current, IDSQ, is set with zero RF drive applied. As P1dB is approached,
the drain current may increase or decrease depending on frequency and dc bias point. At lower values of IDSQ the device is running closer to class
B as power output approaches P1dB. This results in higher PAE (power added efficiency) when compared to a device that is driven by a constant
current source as is typically done with active biasing. As an example, at a VDS = 4 V and IDSQ = 10 mA, Id increases to 62 mA as a P1dB of +19 dBm
is approached.
2. PAE(%) = ((Pout – Pin)/Pdc) x 100
3. Gamma out is the reflection coefficient of the matching circuit presented to the output of the device.
