Overview

ACOM A3x2000A HF Power Splitter/Combiner

The ACOM A3x2000A HF Power Splitter/Combiner 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. This allows for better signal processing, modular amplification setup, and more consistent power levels.
For best results we recommend three automatic amplifiers of the type ACOM2000A. Manual tune amplifiers with a precise tuning indicator like ACOM1200, ACOM1000, ACOM1010 or ACOM1011 can be used. Models that use a broadband input network are recommended.

An automatic protection circuit is implemented in the ACOM A3x2000A, which monitors the three amplifier outputs during operation. In case of an imbalance, the protection circuit cuts the drive to the amplifiers and switches transceiver output to an internal 50 Ohm dummy load. The imbalance power is swamped by powerful resistors until the protection trips. Circuit reset is accomplished by a simple push-button.
