10W VHF DIGITAL Indoor TV Transmitter
1.1 Outline
TY-13010Dworks on VHF band (170-230MHz), output power is 10W. VHF series digital transmitter is a kind of product (meet with euro- standard) that specially designed to supply common or pilot frequency coverage and subsidiary station by consuming small and medium power for terrestrial digital TV transmission. It applies to modulation modes like DVB-S, DVB-S2, nQAM, DVB-T, DVB-T2 and DTMB-T and so on. It is applicable to built-up areas, basement, tunnel and remote mountainous areas. Its main advantages include installation convenience and simple process in debugging and maintenance, etc. And in any combination of multiple antenna-feeder system it can supply local coverage and subsidiary station of wireless digital signal in the blind area.
1.2 Main features
• Wide-band frequency response and low noise design
• Design of low power consumption and linearization advances emitting power of the transmitter and reduces nonlinear distortion.
• Very low group delay feature, suitable for digital signal transmission
• ALC keeps output of constant power, output VSWR detecting protection
• Apply to single-channel or multi-channel VHF digital television transmission system
• Be used in the Wide-band frequency repeating of HFC, AML, or MMDS digital TV signal
• Realize wireless network coverage of digital TV at a low cost.
• Modular design simplifies installation, field services and upgrade.
• Automatic and manual switching backup systems available.
• Build-in lightning protector with current-dividing series power prevents lighting surge and instant overvoltage.
• Indoor type with large LCD panel system real time working condition,maintenance and management of system can be achieved easily.
