  • GaAs FET technology
  • High linearity (class A operation)
  • Good harmonic rejection
  • Isolator for protection against high VSWR
  • Reverse polarity protection
  • Monitor outputs for forward and reverse power detection (DC voltage)
  • Adjustable ALC (automatic level control)
  • ON / OFF control with DC voltage (ON at 5 ... 14 V)
  • Multichannel Multipoint Distribution Service (MMDS)
  • Digital broadcast systems (DVB-T, DVB-S)
  • COFDM systems using modulation types QPSK, QAM
  • Analog 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.
