Power Amplifier KU PA 5358 AL



The new power amplifier KU PA 5358 AL features best performance for digital applications in the 5.6 GHz range. It achieves an EVM of typ. 1.2 % @ 0.5 W average output power and an EVM lower than 2.2 % @ 1 W average output power over the complete frequency band from 5300 to 5800 MHz (measured with single-carrier, 64-QAM, 6 Msps). The power amplifier has excellent rejection of spurious and harmonic signals. Many protection and monitoring features allow easy and reliable handling.

Features

  • GaAs FET technology
  • High linearity
  • Low EVM
  • Isolator for protection against high VSWR
  • Adjustable ALC (automatic level control)
  • Over voltage protection and reverse polarity protection
  • Over temperature protection
  • Monitor outputs for forward and reverse power detection (DC voltage)
  • Logic ON / OFF control (ON at +5 … 14 V DC)

    Applications

  • Digital transmission and broadcast systems (DVB, WiMAX)
  • COFDM systems using QPSK, QAM
  • Analog transmission systems
