DAB Transmitter System Contains:

COFDM Modulator DAB-MOD-3000
DAB DRIVER 4000 RF Preamplifier/Controller
Output Power Amplifiers DAB-202-OPA
Output Combiner/Coupler
Output Bandpass Filter

The DAB-TX4000L from UBS is a modular solid-state transmitter amplifier system, designed to meet present and future market demands. The modular Transmitter configuration enables to meet all DAB system requirements with future upgrade capabilities. The module designs are conservative with reserve cooling capacity yet the overall assembled system is both powerful and compact. System trouble shooting and module replacement is straightforward due to ready access to all interconnects.

The DAB-TX4000L contains the following building blocks:

COFDM Modulator DAB-MOD-3000, which performs input signal processing, generates RF output in L-Band frequency range and provides complete Transmitter monitoring and control
DAB DRIVER 4000 – RF Preamplifier/Controller, which distributes the RF signal to output amplifiers, provides total amplifiers control and maintains the output power level
Output Power Amplifiers DAB-202-OPA, 3 units per Transmitter, provide RF signal amplification up to required output power level
Output Combiner/Coupler – combines RF signals from the amplifiers and measures output power level
Output Bandpass Filter rejects out-off-band spectrum components
Power Distribution Module DAB-4000-PDU routes AC Line Input to all Transmitter modules

DAB-TX4000L provides RS232 Local Service Interface and Ethernet 10BaseT WEB Interface for Transmitter remote control. DAB-TX4000L is assembled in a 19" Rackmount Case equipped with the shock absorbers and removable castor wheels for easy transportation.
