Linear Power Amplifier for the S-Band KU PA 3436 A



This power amplifier provides high linearity. An isolator at the output protects the semiconductor devices from reverse power. Very good harmonic rejection is achieved. Two detector outputs allow permanent monitoring of forward and reverse power. Typical applications of this amplifier are digital broadcast and communication systems like Digital Video Broadcast (DVB) or Digital Multimedia Broadcast (DMB). The amplifier contains an automatic level control (ALC). The desired output power can be adjusted continuously, from nearly zero to the maximum output power.

Features

  • GaAs FET technology
  • High linearity (class A operation)
  • Good harmonic rejection
  • Isolator for protection against high VSWR
  • Over voltage protection and reverse polarity protection
  • Monitor outputs for foward and reverse power detection (DC voltage)
  • Adjustable ALC (automatic level control)
  • ON / OFF control with DC voltage (ON at 5 ... 14 V DC)

    Applications

  • Digital broadcast systems (DVB, DMB)
  • COFDM systems using modulation types QPSK, QAM
  • Analog transmission systems
  • With reduced power suitable for DATV (digital amateur television)
