Product Specification
Low Frequency Power Handling: Z
Figure 4 provides guidelines of how to adjust the Vdd
and input Power to the 42552 device. The upper limit
curve represents the maximum Input Power vs Vdd
recommended for this part.
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 100kHz from Fig. 5 is
10dB
The max power handling at Vdd = 3V is 5.5dB from

Derate power under mismatch conditions
Total maximum power handling for this example is
10dB + 5.5dB = 15.5dBm
