Product description
200w Analog TV Transmitter Upgrade
This transmitter is an indoor UHF Digital Terrestrial Television (DTT) transmitter/gap filler with up to 300W of output power, and is designed for small-scale or blind area coverage application in DTT broadcasting.
This 200W digital TV transmitter utilizes the state-of-the-art LDMOS devices and compact 4U rack-mount structure that enables DTT operators to have reduced energy cost and with much less occupied space of equipment in their DTT network. This series supports various DTT modulation standards, such as DVB-T/H, DVB-T2, DTMB, ATSC, ISDB-T/Tb, and also can operate in SFN mode enabling less spectrum resource is used.
Overview:
This product is the all solid-state Single-channel TV Transmitter, it adopts professional TV exciter, and it can use the
single/duel exciter configuration, switching automatically.
This transmitter has a variety of linear and non-linear pre-correction function, carrier frequency offset, and precision bias
(with external precision reference source) function.
It can prefabricate and control the half-power output, and it has remote control telemetry interface.
The power amplifier used LDMOS FET, the analog and digital are both compatible, and it used high-quality switch parallel power.
The power amplifier and power supply are both used hot-plug devices.
The power loss and standing wave of the one-time synthesis power combiner is small.
The module of power amplifier display the working parameters in real-time.
The whole machine has the protection of over-current, over temperature, over power and over-standing wave ratio.
The master touch screen displays the working parameters of the whole machine and the module of power amplifier (PA) in real-time.
The 200W transmitter is installed in one 19inch chassis; it’s suitable for medium or small TV station.
Features:
Supported Standards DVB-T,DVB-T2,DVB-H,DTMB,ATSC,ISDB-T
All solid-state digital TV transmitter, bandwidth is 6-8MHZ.
Pre-distortion correction, dual-exciters switch automatically.
High Linearity LDMOS Power Amplifier, high-gain power amplifier module, parallel switching power supply, it is a high-efficiency
transmitter.
