The antenna port power is 15W(41.8dbm) of my product.
The last PA peak capabiltiy is 52dBm.
The orignal signal PAR is 11dB before CFR module.
I enable the CFR algorithm，CFR work normally，The signal PAR is 8.5db after CFR module normal work.
I enable DPD algorithm,we use 95coeffs. when the antenna port power is 35dbm,TU PAR is 8.8db, TX PAR is 9db，DPD status is normal.
when the antenna port power is 40dbm,TU PAR is 8.8db, TX PAR is 14db，DPD status is abnormal, ACLR is fail.
why the signal PAR is expanded so much after DPD algorithm?
Could you give me some suggestion.
Thanks in advance.
