Linear Power Amplifier MKU PA 34100 A



This new power amplifier using LD-MOSFET technology provides high linearity and high efficiency (up to 40 %). 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.

Features

  • High voltage and reverse polarity protection
  • Built-in directional coupler with detector for monitoring the output power - MON -
  • Milled aluminium case
