Linear MOSFET Power Amplifier KU PA 2021 LD

This new developed power amplifier, equipped with LD-MOSFET´s, is characterised by high linearity of the output signal and by high efficiency. This amplifier module is thermally very stable and can be used due to their high linearity for all operating modes, especially SSB/ DATV / DVB-S / DVB-T.
The 28 V LD-MOSFET-Technology make these good technical datas possible.
