The ACOM 3x2000A is an HF power splitter/combiner which is a passive device designed to sum the outputs of three HF linear amplifiers into a common load while the amplifiers are driven by a single exciter.

Easy to operate
There is no difference from the operation of a three times more powerful single amplifier.

For optimal operation of the combiner, three amplifiers with similar characteristics are needed. The three signals must be coherent and have close amplitudes, and their phase differences must be small enough so that there is no excessive loss of useful power in the ballast loads at the combiner output. In 3x2000A this is achieved by dividing the common input signal from the transceiver into three same channels by the input-power splitter and using three identical amplifiers per channel. For best results, we recommend three automatic amplifiers of the type ACOM 2000A.

We recommend to using ACOM 3x2000A power splitter/combiner with the following ACOM amplifier models:

  • 2000A | Automatic HF Linear Amplifier;
  • 2100 | HF + 6 m Linear Amplifier;
  • 1500 | HF + 6 m Linear Amplifier;
  • 1000 | HF + 6 m Linear Amplifier;
  • 1010 | HF Linear Amplifier.


All these models use a broadband input network which sets minimum phase differences between the units.

Automatic protection
An automatic protection circuit is implemented in the ACOM 3x2000A, which monitors the three amplifier outputs during operation. In case of an imbalance, the protection trips thus cutting the drive to the amplifiers and switching the transceiver output to an internal 50 Ohm dummy load. The imbalance of power, both input, and output, is swamped by powerful loads until the protection trips. Therefore the transceiver and the three amplifiers are well protected. After fixing the trouble you can resume operation by pressing the button RESET.

Mounting possibility–the cabinet is NLA
As an option, a metal rack (shown on the cover page), designed for housing three ACOM amplifiers (preferably the ACOM 2000A model) and the ACOM 3x2000A splitter/combiner, is available. The rack is built with four identical slots. Matching black anodized, machined aluminum facia perfectly accents the amplifiers and splitter/combiner. Heavy-duty casters provide easy movement and transport.
