Features
High downlink power of 52dBm for extended cell coverage. MCPA with 20MHz Instantaneous Bandwidth can support up multiple downlink
carriers. Supports GSM, EDGE, CDMA and WCDMA signal. 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 PA 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-1900(MCPA) 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), surge protector, 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-1900 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: Channel No, 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, Door Open, DL Input Power Low, DL Output Power Low, and Over Temp), UL/DL Gain, DL Input /Output Power.
The TC-1900 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.
