KU PA 2345 A

Linear MOSFET Power Amplifier

2300 ... 2500 MHz • 40 W

This new power amplifier using LD-MOSFET technology provides high linearity and high efficiency (up to 50 %). Since the amplifier is thermally very stable and highly linear, it can be used for all operating modes. Typical applications are DAB / COFDM / QPSK / DATV / DVB-S / DVB-T.
