Linear Power Amplifier MKU PA 34350 CU

Thisnew power amplifier, which is based on LD MOS technology, ischaracterized by high linearity and best performance. The amplifiermodule is thermally very stable. Due to the high linearity, it can beused for all operating modes, like SSB, CW or DATV (digital amateurtelevision) or other digital modes. In contrast to conventional tubeamplifiers, no high voltage transformers and other dangerous componentsare needed

Thepower amplifier can also be used within professional applications likedigital video broadcast (DVB) or other communication systems usingCOFDM and digital modulation.
