The requirement would be for 60 dB or better after correction...and 
enough stability to ensure the correction actually works. In talking to 
them...they hadn't gotten that far, yet.

BTW, we use feedforward amps with LDMOS in our products with 20W average 
and about 200W PEP and achieve about -65 dBc IMD.
