Features
◎ Accord with DVB-T ETS300 744 standard.
◎ Digital TV RF stream ASI serial connecter and SPI parallel connecter
◎ 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.
◎ With over-voltage, over-current, over-heat and over-high standing wave ratio protection, the equipment can work securely.
◎ With digital/analogue compatible output band-pass filter, adopted high-power synthesis technology, with low insertion loss and high out-of-band suppression.
◎ Support SFN and MFN network.
◎ Support ALC, AGC as different conditional.
◎ Support compelled-wind cool design, with low power consumption and low noise.
◎ Al-alloy cover designed, rain-proof, damp-proof.
◎ Remote control, GSM alarm, optional.
