ALOS-2 PALSAR Coherency Matrix Generation

I am processing ALOS-2 PALSAR full polarimetric data for a scene which has snow cover. When, I generate the coherency matrix, the matrix components shows abnormal scale of values . I converted the components to dB scale and the range is around 100-145, while realistically it should be around 10 to -30. Any inputs are highly apprreciated.
Thanks a bunch!

Did you calibrate the data before matrix generation?
You can output to complex data in the radiometric calibration module. Maybe polarimetric angle correction should also be applied beef before.

Is it a Level 1.1 product?

Yeah, the calibration did the trick. Thanks a lot ABraun.
