The RH6133 is a solid state, cost effective, broadband power amplifier designed to meet the new standards of software reprogrammable radios to satisfy the performance required in the use of HF radios in modern, digital communication systems.

The RH6133 has proven performance used as a standard RF amplification module. The RF Amplifier/Power Supply is a self-contained unit suitable for tabletop or 19” rack installation.

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
  • LCD monitor
  • 2 –levels overheat protection
  • Short/open output protection
  • Continuous operational cycle at full output power
  • High reliability in harsh environment

The RH6133 capable to be matched with various HF radios: MICOM-2/3, CODAN NGT, Barret 2050 and later, ICOM. Other models can be matched by customer’s request.
