The RH6132 is a solid state, cost effective, broadband power amplifier

designed to meet the new standards of software defined radios to satisfy the performance required in the use of HF radios in modern, digital communication systems.

The RH6132 has proven performance used as a standard RF amplification module.

Broadband RF amplification with the complete elimination of tunable elements gives the family’s components the frequency agility characteristics required by ALE (Automatic Link Establishment) operation over the HF band.

The main features of the amplifier are:

  • Built-in controller
  • LED indicators
  • 2 –levels overheat protection
  • Short/open output protection
  • Continuous operational cycle at full output power
  • High reliability in harsh environment
