Could you provide the ACPR results of HMC8500PM5E? espeically for the LTE mode. thanks

I think that your power levels are a bit unrealistic. Or to put it another way, the ACP that you will get at these power levels will be very poor. 5 Watts is +37 dBm. A typical LTE carrier has a peak to average ratio of around 11 dB. So the peak power will be 48 dBm. HMC8500 has a PSAT of around 40 dBm and the PSAT of HMC1114 is around 42 dBm. Even if you are using DPD and crest factor reduction, I think that your target output powers are too close to the saturation point.)
