Features

High downlink power of 55dBm for extended cell coverage.

MCPA with 20MHz Instantaneous Bandwidth can support multiple downlink

carriers.

Low noise amplifier reduces uplink system noise figure and results in reduced

call drops and improved voice quality.

Reduces handset output power and improved BTS uplink receiver sensitivity.

Permits local monitoring via PC at tower bottom and remotely by wireless

modem.

Alarms can be transmitted to OMC via data link or SMS.

Automatic bypass feature permits BTS operation when booster or power supply

fails.

Internal Li-ion backup battery ensures alarm messages are transmitted when

power is down.

Designed for all outdoor installation– waterproof, damp-proof and omni-sealed

(IP54)

Product Description

TC-9100 GSM900 band-selective Base Station Power Amplifier provides both uplink and downlink amplification for

multiple carriers and extends the coverage that decreases the cost and improves the service quality. The unit is fit for

outdoor installation and can 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.

The unit is powered by both AC and DC power supply options, including 110/220VAC and -48VDC. It consists of duplexers

(DPX), uplink LNA, downlink MCPA, RF by-pass switch, Main Control Unit (MCU), distribution board, power supply unit

(PSU), wireless modem and Li-ion backup battery. Parameter settings can be done locally via a PC with installed OMT

software, or remotely via wireless modem using OMT or OMC software. Through the wireless modem, the alarm data can

be transmitted to the OMC automatically, or be sent as SMS to a predefined cellular device.

Operation and Maintenance

Using a direct serial connection to a PC, installation and commissioning of the TC-9100 is accomplished by the OMT. Using

the integrated wireless modem (data or SMS mode), equipment parameters can be monitored and controlled remotely.

Controlled equipment parameters include: UL/DL ATT, Soft ON/OFF, Over-Temp Threshold, DL Output Power Threshold,

DL Input Power Threshold and Alarm Report Enable.

Monitored equipment alarms and parameters include: Alarms (LNA, DL PA, Power Down, PSU Fault, DL Input Power Low,

DL Output Power Low, Over Temp), UL/DL Gain, DL Input /Output Power.

The TC-9100 has been developed to take advantage of advanced network operation, where the OMC (optional) provides an

effective solution for central monitoring of a group of Comba products.
