300W Outdoor MMDS DTT Digital TV Transmitter for Wireless TV Broadcasting System


HORRAY’s MMDS broadband transmitter has stable performance, with complete range of functionalities and great variety; it can support single or multiple channel transmission


HTM-300D MMDS Outdoor Digital Transmitter is a kind of digital facility working on S band (2.0-2.9GHz). This equipment adapted latest generation power amplifier chip LDMOS. It supports both analog and digital modulation and adapts to multiple modulation modes like DVB-S/S2, DVB-T/T2, DVB-C, ISDB-T/TB and etc. AGC function guaranteed the reliable operation of the equipment by maintain constant power output of transmitter. It also has auto-alarming and lightning-proof functions. As the advantages mentioned above, this equipment can widely apply to point to point and point to multi-point transmission and signal coverage.


Main features:

  • With optional SMS module can monitor the abnormal values real-time.
  • Adapted new generation power amplifier (transmitting power increased and un-linear distortion effectively decreased).
  • Aluminum 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.
  • Extended interface for remote control.
  • Small in size, easy for construction and maintenance.
