KU PA 240250-100 B, RF Power Amplifier

2400 ... 2500 MHz • 100 W

This power amplifier using LD-MOSFET technology provides high linearity and high efficiency (up to 45 %). 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.
