A.Giới thiệu sản phẩm
Bộ lọc song công Duplexer, bộ khuếch đại công suất (PA) và bộ tản nhiệt hiệu suất cao cho hệ thống RRU (Remote Radio Unit) là kết quả nghiên cứu, thiết kế, chế tạo do Trung tâm Công nghệ Vi điện tử và Tin học thực hiện.
Việc làm chủ thiết kế, chế tạo bộ lọc song công Duplexer, bộ khuếch đại công suất và bộ tản nhiệt hiệu suất cao cho hệ thống RRU là tiền đề để hình thành và phát triển ngành công nghiệp gia công các thiết bị viễn thông công nghệ cao tại Việt Nam, thiết bị thu phát 4G và tiến tới 5G trong tương lai gần. góp phần cung cấp giải pháp công nghệ cho các nhà mạng Viettel, Mobifone và Vinaphone đang khai triển mạng viễn thông 4G-LTE Macro cell phủ sóng cả nước rất mạnh mẽ. Song song với việc nhập các thiết bị của Ericson, Nokia, Huawei, các nhà mạng cũng từng bước chủ động sản xuất thiết bị và tiến tới làm chủ công nghệ lõi, một trong những công nghệ đó là công nghệ thiết kế và sản xuất phần cứng.
