MMIU FOR MICRO-BTS(MASTER MUCRO-BTS INTERFACE UNIT) |
| |
|
| |
Description |
| |
| •
This unit is MMIU(Master Micro-BTS Interface
Unit) for Micro BTS. MMIU amplify the
TX signal of BUDA Board with distinguish
each sectors and control the gain of
TX path with consider path loss to Remote.
Also, MMIU receive the signal from Remote
through 2-path respectively, amplify
the signal for compensate path loss
and divide the signal through 2-way
divider. |
