The ADL5610/1, ADL5544/5 exhibits the best linearity/IP3 at an output power
level of ~0dBm. Is the device designed for a specific output power level? 

 

The ADL5610/1, ADL5544/5 incorporate a harmonic cancellation circuit which
improves OIP3. The drawback to this approach is that the optimization is
limited to a particular frequency and not the entire bandwidth of the
amplifier.  It is expected that someone using the device would operate around 0
dBm output power. This would allow for large crestfactor swings WCDMA type
modulated signals and not drive the amplifier beyond its 1 dB compression
point.
