Linear Power Amplifier MKU PA 3440 A



Thisnewpower amplifier using LD-MOSFET technology provides high linearityandhigh efficiency (up to 31 %). Since the amplifier is thermallyverystable and highly linear, it can be used for all operatingmodes.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
