3.2.5 Transmitting filter
The DIB-R5 advanced offers a high degree of flexibility and enables demand-oriented
variants with respect to antenna configurations.
Depending on the antenna configuration, different transmitting filters are used that are
required for transmitting and receiving. Only one of the two transmitting filters is used in
the process.
One of the following transmitting filters is used in the DIB-R5 advanced:
n
Ä
DUPLEXER

Ä
TX FILTER
3.2.5.1 DUPLEXER
The DUPLEXER is used for separating the receiving and transmitting paths and is used if
a common transmitting/receiving antenna (Tx/Rx antenna) is used.
The following figure shows the front view of the DUPLEXER. The following table
describes it in detail.
