1 GENERAL INFORMATION
TB-1800 GSM1800 tower mounted booster provides both uplink and downlink amplification for two
carriers. The unit is installed near the antenna at the tower top to boost the transmitted power to extend
cell coverage. The uplink low-noise amplifier (LNA) serves to improve the receiver sensitivity of the
BTS to cope with the extended cell coverage in the downlink. Typically serving two applications: using
two service antennas with one carrier each to cover the same cell for higher output power, or using two
service antennas with a hybrid coupler combined two carriers each to cover two different cells.
The unit is powered with various power supply options. TB-1800 comprises of duplexers, uplink LNA,
downlink PA, RF bypass, Main Control Unit (MCU), power supply unit, surge protection, wireless
modem and Li-ion backup battery. Remote configuration and surveillance is possible through Comba’s
remote control and monitoring system, via PC or wireless modem to the OMT/OMC.
Main features of TB-1800:
TB-1800 is a high quality TMB with the following features:
zDownlink power of 40dBm, 43dBm or 46dBm per carrier.
zLow noise amplifier reduces uplink system noise figure and results in reduced dropped call and
improved voice quality.
zReduces handset output power for improved uplink C/I.
zPermits monitoring via PC and remotely with wireless modem.
zAlarms can be transmitted to OMC via data link or SMS.
zVoltage-free relay connection for external alarm.
zRF bypass maintain BTS operation under fault conditions.
zIntegrated Li-ion backup battery ensures alarm messages are transmitted during power failure.
zDesigned for all weather installation – waterproof, damp-proof and omni-sealed.
There exist different variants of TB-1800 products, each serving a specific application, shown as
follows:

ENU Status : 1-0-0
Typical TB-1800 units consist of the following components:
Duplexer (DPX):
DPX is installed in the side of ANT port. It is used to combine/divide the uplink and downlink signals.
DL Power Amplifier (PA):
It fulfils power amplification in downlink branch.
UL Low Noise Amplifier (LNA):
Low Noise Amplifier (LNA) is installed in the UL branch to amplifier uplink signals.
Power Supply Unit (PSU):
The PSU converts the input 220VAC, -48VDC or +24VDC into stable DC to supply power to PA, LNA,
MCU and charge Li-ion battery.
RF Switch
A bypass switch module is installed in each carrier. It is activated when there is a fault with the LNA, PA
and/or PSU, or when the power off and/or over temperature happen.
VSWR Alarm Module
Generates alarm for abnormal VSWR levels.
Main Control Unit (MCU):
The MCU is used to monitor and control the operation parameters of the TB-1800 and provides
telecommunication interface for remote control and indicator. LED indicators (L1~L4) indicate the
respective operation status.
Surge protector:
The surge protector is mounted next to the PSU. Within it there are three connections: Live, Neutral
and Grounding. This provides protection to the PSU. It is assumed the antenna system will have ample
lightning protection themselves.
Wireless Modem:
It is mounted adjacent to MCU, it has connection of RF, data and power. It is used for remote control
and the MCU sends out alarms to OMC via the wireless modem. On the wireless modem there is an
indicator LED to show modem status.
Li-ion Battery:
The Li-ion battery-pack is enclosed within a plastic cover and provides back-up supply to the MCU for
up to three hours in the event of mains failure.
Distribution Board:
The distribution board serves as a distributor for power and internal communication and connectivities
to the function modules, MCU, RS232 port for local control.
