The ACOM3x2000A is a 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. There is no difference from the operation of a three times more powerful single amplifier.
For proper operation, the combiner requires three amplifier outputs having equal amplitudes...
The ACOM 2000A Automatic HF Linear Amplifier is the world's most advanced HF amplifier designed for amateur use. The ACOM 2000A is the first amateur HF amplifier to include both fully automatic tuning and sophisticated digital control capabilities. This revolutionary new amplifier delivers maximum legal power in all modes and operates on all HF amateur bands.
A New Standard in Amplifier...
Easy to operate
The TRI is a powerful tuning aid that, together with the automatically controlled input attenuator, helps the operator to quickly and precisely match the antenna impedance to the optimum tube load impedance (5-10 seconds typically). The auto-operate function (when enabled) maintains the amplifier in the OPERATE mode for you, thus avoiding unnecessary manual operations.
FlexRadio 1500W Solid State Amplifier (Power Genius XL™)
The Power Genius XL is a 100% duty cycle, legal limit (1500W) 1.8-54 MHz RF amplifier intended for both amateur and government use. It incorporates a pair of modern BLF188 LDMOS transistors that are individually capable of 1.5 kW thus providing plenty of headroom for lowest IMD and spurious output. Efficiency and spurious performance...
