ARX digital repeaters for complete restoration, as the DVB signal is received and re-transmitted

The ARX series of regenerative digital repeaters features built-in error correction via the intelligent COFDM modulator that provides error-free retransmission of multi frequency DVB networks. The error-corrected transport stream is also available via ASI output for local re-multiplexing, or monitoring purposes. The modulator allows the repeater to function as a transmitter. Low power applications are available in compact designs up to 100 W rms; the range of LDMOS power amplifiers offers scalable solutions up to 10 kW rms, as air cooled or liquid cooled repeaters.

Options for arx repeaters

• RF output filter in non-critical and critical mask configuration
  non-critical and critical mask filters
  
  
• GPS receiver with GPS antenna - when operating in SFN view technical documentation in PDF;
• UPS for exciter - excellent solution to avoid long time syncronization to GPS satellite after power supply break view technical documentation in PDF;
• GSM modem - sending SNMP traps over SMS protocol view technical documentation in PDF;
• Supervising the repeaters on site - use rackmountable computer and rackmountable keyboard view technical documentation in PDF.

exciter

The exciter is housed in a compact 19” 3U rack mount and with the A class amplifier provides 5 W of UHF output power (0.1 W for VHF). The high sensitivity input tuner provides optimized reception of the RF DVB signal. The DVB signal is completely demodulated to MPEG-2 or MPEG-4 TS and error-corrected before retransmission in a fresh COFDM spectrum. Errorcorrected MPEG-2 or MPEG-4 TS is available via ASI output for local re-multiplexing.

ASI input allows the repeater to function also as a transmitter.

Other functions and performances are the same as for Elti digital transmitters SKY®.

power amplifier

External amplifiers are available from Elti digital transmitters SKY®.

compact repeaters

The compact repeater includes the RF down-converter, exciter functions, the power amplifier and output filter internally. It is available in a compact 19” 3U rack mount and with the A class amplifier provides up to 5 W of UHF output power or in compact 19” 4U rack mount with the AB class amplifier that provides up to 150 W of UHF output power (300 W for VHF).
