1. Introduction
1.1. General Introduction
As an equipment to clear RF shadows inevitably generated between the adjacent cells of
CDMA, STR250R01C supports CDMA and effectively repeats the signals between mobile
terminals in weak coverage area and BTS.
This equipment is Dual Band Optical DAS that support 850MHz and 1900MHz bands
simultaneously, and it is designed to support CDMA for each band.
This equipment provides the effective and flexible solution to service providers to
improve quality of service for their subscribers.
The main objectives of STR250R01C are as follows:
-Expansion of coverage
-Enhancement of service quality in areas such as tunnels or in-building
-Improvement in signal strength at places where the signal level is less than desired.
-Support dual bands of 850MHz and 1900MHz.
-Support single mode of CDMA for each band.
-RU power consumption and RU size optimization by built-in Crest Factor Reduction
(CFR) technology for the CDMA signal.

4.1.4. Description of STR250R01C RHU
[Forward Path]
The signal from CDMA BTS is fed to the RF link antenna port of RHU. First, RHU
Filter rejects the unwanted signal. Then LNA and Up-down converter make gain for
transmitting. Combiner combines the signal with the modem signal (360MHz). The
combined signal gets transmitted to RU via optical cable.
[Reverse Path]
The CDMA RVS signal input from RU through the optic module is separated into RF
and modem signal, and then RF RVS module performs optic AGC and RVS HPA
makes large signal level for transmitting. Finally RHU Filter rejects the unwanted
signal and RHU link antenna outputs RVS RF signal. The RF signal then is fed to the
BTS.
