  • GaAs FET technology
  • Isolator for protection against high VSWR
  • Reverse polarity protection
  • Monitor output for forward power detection (DC voltage)
  • Logic ON / OFF control (ON at 5 ... 14 V)
  • Digital broadcast systems (DVB-T, DVB-S)
  • COFDM systems using modulation types QPSK, QAM
  • Analog and digital transmission systems
Please notice the following:
  • The technical specifications refer to room temperature.
  • The power amplifier doesn’t contain any coaxial relays.
  • The recommended combination of heat sink and fan(s) is only specified for an ambient temperature of 25 °C.
  • Further information about dimensioning of heat sinks is available on our FAQ site.
