About ACP & PAE of HMC8500 for LTE

Dear Sir,

We have test the ACP & PAE on EVB of HMC8500 as attached. As data, the ACP is insufficient at 30dBm(1W) output power under LTE signal (1.5GHz, 64QAM@20MHz ), which is back off 40dBm(10W) around 10dB. Due to limit dimension of project, DPD can't been used on. In order to improve that, do you have any recommend of input matching on frequency 1.3GHz~1.5GHz or load-pull be provided ? Or others can meet the specification of 35dBm output under LTE @20MHz during 1.3GHz~1.5GHz ?  Thanks.
