hi,
ADS Software model of SD57060 shows that the device is unstable at 945MHz. To get stability factor greater than one over the desired band , i add 3 ohm resistor at the gate side. After stabilizing it load pull test shows that maximum power can not be achieved using 3 watt input power as shown in the device datasheet. Why datasheet shows maximum power without stabilizing the device
