4.1.3. Descriptions of CM150D-01 DU
[Downlink Path]
The signal from GSM or WCDMA BTS is fed to the RF input port of DU. It becomes the
input signal to the optic module to be transmitted to RU.
[Uplink Path]
The optical signal from RU (GSM or WCDMA) is converted into RF and becomes the input
signal to the BTS of GSM or WCDMA.

4.2.3. Description of CM150D-01 RU
[Downlink path]
The optical signal is converted into RF and linearly amplified at HPA, passed through the
Duplexer, and finally transmitted through an external antenna.
[Uplink Path]
GSM and WCDMA signals incoming from an antenna are first passed by the Duplexer and
then transmitted to DU through the optic module.
