The Barrett high power 2075 HF transmitters can be set to deliver 500 W or 1 kW PEP output power from 2 to 30 MHz in all modes and at 100% duty cycle. The transmitters come as a complete package with a 2050 high duty cycle exciter, power supply, RF linear power amplifier; interconnect cables, AC power distribution panel and all rack mount hardware.
The RF power amplifier is a rugged solid state unit with a comprehensive LCD display that displays the amplifier operating parameters. No tuning adjustments are required and the amplifier’s ALC system protects the unit from severe mismatches.
The switch mode power supply operates from supply voltages between 90 to 250 VAC with no switching and at all power levels.
Fully automatic filter selection over the frequency range when connected to the Barrett 2050 transceiver.
Reliable MOSFET power amplifier modules fully protected against bad antenna VSWR overvoltage and temperature.
High power exciter with highly efficient heat sinking and high volume fan units in the rack enclosure provide cool operation under all conditions.
Efficient switch mode power supply that operates 90 to 250 VAC without adjustment.
The 2075 transmitter has 600 ohm balanced audio inputs and an RS-232 control port with a full range of control commands. PTT is provided by a physical input line or by RS-232 control.
A 1 kW antenna tuner with memory options (Barrett P/N BC207510) and opto-coupled interface is available for use with the 2075 high power transmitter.
A 1 kW broadband dipole (Barrett P/N BC91703 or BC91207) with frequency coverage of 3.6 MHz to 30 MHz and 2 MHz to 30 MHz respectively is available for use with the 2075 high power transmitter.
