I believed that you should familiar to AIS process coz we are one of AIS approved vendor list for diplexer. Anyway, K.Suchat is our project director who can share you the process that we did before.
For model 4-6, this is a special request from NSN to Tongyu to provide samples for this testing coz this would be good & big opportunity for them as we did try many years so far. It would be great if we can have F2F discussion about this issue but I’m not available by Friday…Can it be on Monday afternoon?
