Figure 4 provides guidelines of how to adjust the
Vdd and Input Power to the PE42556 device. The
upper limit curve represents the maximum Input
Power vs Vdd recommended for this part at low
frequencies only. Please consult Table 3 for the
1 MHz ≤ 13.5 GHz range.
Figure 4. Maximum Operating Power Limit
To allow for sustained operation under any load VSWR condition,
max power should be kept 6dB lower than max power in 50 Ohm.

Figure 5 shows how the power limit in Figure 4 will
increase with frequency. As the frequency
increases, the contours and Maximum Power
Limit Curve will increase with the increase in
power handling shown on the curve.

The power handling offset for 100 kHz from
Fig. 5 is 7 dB
The max power handling at Vdd = 3 V is 5.5
dB from Fig. 4
Derate power under mismatch conditions
Total maximum power handling for this
example is 7 dB + 5.5 dB = 12.5 dBm
