Description
Wireless TV UHF DVB-T/T2 Digital Transmitter for Signal Transmission
Overview




TY-17XXA/B Wireless TV UHF DVB-T/T2 Digital Transmitter belongs to UHF band series transmitter, which is a kind of product(meet 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.
The series transmitter has optional power level from 10W to 500W, indoor type and outdoor type can meet with different users, and support multiple modulation modes, eg. DTMB, DVB-C, DVB-S/S2, DVB-T/DVB-T2, ISDB-T/ISDB-Tb and etc.. 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. In addition to being widely used in domestic all-level television stations and network companies, it has exported in bulk to places like southeast Asia and Africa.
Main Features:
- 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 UHF digital television transmission system.
- Indoor type with touchable LCD control panel to adjust the key parameters:Output power range,Input level range,AGC range and monitor the abnormal values real-time.
- Standard 19″ structural design, with natural heat dissipation or forced air cooling design, equipment operational reliability can be improved.
- Signal debugging design (maintenance can be simply carried out).
- Simple debugging procedure, signal opening can be achieved without specialized instruments.
- Multiple choices in power level and local frequency meet with different requirements.
- Extended interface for remote control.
-
Wide-band frequency response and low noise design.
-
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.
