About confidentiality of Internal Photos We request confidentiality of Internal Photos for the subject application. Our equipments are Base Station and User Terminal for wireless internet system (iBurst system), and these equipments need high RF performance for accomplishing high performance of iBurst system. Especially a TRx Board or a PA Module of Base Station needs high RF performance. We design RF circuits to keep this performance from increasing Spurious Emission and decreasing isolation. We have know-how for pattern of RF line on printed board. And this know-how is very important. So we don’t desire to open “internal photos”. Please confidentiality of Internal Photos.
