Outline
CS***1 DVB-T transmitter is used for digital TV terrestrial wireless transmitting system. It can work with COFDM modulator, transmitted digital channels to the digital TV receiver for not-long distance transmission with high broadcasting quality..
Features
â—Ž Accord with DVB-T ETS**0 **4 standard.
â—Ž Digital TV RF stream ASI serial connecter and SPI parallel connecter
â—Ž With whole solid-state circuit design, super-linearity, broad-band power amplifier unit and power amplifier modularization design. Adopted LDMOS high-power tube with great redundancy, easy to install or maintain.
â—Ž With over-voltage, over-current, over-heat and over-high standing wave ratio protection, the equipment can work securely.
â—Ž With digital/analogue compatible output band-pass filter, adopted high-power synthesis technology, with low insertion loss and high out-of-band suppression.
â—Ž Support SFN and MFN network.
â—Ž Support ALC, AGC as different conditional.
â—Ž Support compelled-wind cool design, with low power consumption and low noise.
â—Ž Al-alloy cover designed, rain-proof, damp-proof.
â—Ž Remote control, GSM alarm, optional.
