Linear Power Amplifier MKU PA 23400 A

This new power amplifier, which is based on LD MOS technology, is characterized by high linearity and best performance. The amplifier module is thermally very stable. Due to the high linearity, it can be used for all operating modes, like SSB, CW or DATV (digital amateur television) or other digital modes. In contrast to conventional tube amplifiers, no high voltage transformers and other dangerous components are needed. The output power can be increased to 800 watts by using two power amplifier modules MKU PA 23400 A and 90° hybrid couplers. The power amplifier can also be used within professional applications like digital video broadcast (DVB) or other communication systems using COFDM and digital modulation.
