300W Indoor MMDS Digital TV Transmitter for Wireless TV
HTM-300I 300W MMDS Indoor 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, QAM, ISDB-T/TB and etc. AGC/ALC
function guaranteed the reliable operation of the equipment by
maintain constant power output of transmitter. Its LCD display
shows the parameters of output power, working voltage and AGC, can
monitor the abnormal values real-time. 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.
· 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.
· 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
· 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.
