DVB-T/H TV amplifier



Description


The D50/D100/D200 is a full LD-MOS Broadcast Power Amplifier designed for both digital and analog application. The output stages are designed using exclusively LD-MOS technology, which ensures high basic linearity and stability of the amplifier characteristic. A built-in protective circuit safeguards the amplifiers against reflecton and overheating. The unit is the state of the art in terms of easy assembly, reliability and performances. The complete unit can assure the compliance to all relevant international standards. The D50/D100/D200 is built on single power amplifier modules of 50/100/200 W for DVB-T/H. All amplifiers are broadband in the 470 MHz to 862 MHz range. Both the power supply and the cooling system are integrated into the amplifiers, thus requiring no peripherals. This enables flexible instalation in a standard 19 -inch rack or even operation without any rack at all. With the D50/D100/D200, the customer can comfortably operate the amplifier with the color display and the buttons.
