This state-of-the-art solid-state linear amplifier is at the forefront of RF engineering, designed to offer unrivalled performance, convenience, and reliability. Operating across a broad frequency range (1.8 MHz to 50 MHz, including WARC bands and 60 m where permitted), it provides a solid 1.5 kW of output with exceptional linearity, efficiency, and robustness. Integrated with a built-in power supply and a highly capable automatic antenna tuner, it is remarkably compact and lightweight for its class, measuring just 28 cm (L) x 12 cm (H) x 38 cm (P) and weighing approximately 9.5 kg.

Two powerful CPUs manage over 30,000 lines of software code, delivering an unparalleled suite of automated features. The amplifier seamlessly integrates with popular transceiver brands—ICOM, YAESU, KENWOOD, TEN-TEC, FLEX-RADIO, ELECRAFT—and even home-made rigs, eliminating the need for manual band switching, tuning, and antenna selection. Simply turn the frequency knob on your transceiver, and let the amplifier handle the rest.

Beyond user-friendly operation, this amplifier is built for durability and safety. It employs advanced hardware and software protection mechanisms, constantly monitoring parameters like SWR, temperature, voltage, and current. Cooling is managed intelligently with linear fan speed control, ensuring quiet operation even under heavy load. There is no warm-up time, and the unit is always ready for instant performance. Featuring SO2R capability, two RF inputs, and a highly accurate, fully automatic internal tuner capable of matching up to 5:1 SWR (on HF) and 2.5:1 (on 6 m), this amplifier offers unparalleled versatility. Its switching power supply with PFC accepts input voltages from 100 to 255 VAC, enabling use in various regions without performance compromise.

Coupled with a detailed LCD display for real-time monitoring, easy software updates via USB/RS232 ports, and a durable carry-bag for portable operations like Field Days or DXpeditions, this amplifier is the ultimate solution for both serious HF operators and those seeking top-tier convenience.

What Sets It Apart from the Standard 1.5k-FA Model

The key difference in this special version lies in its internal power devices. Unlike the standard 1.5k-FA model, this variant uses Double MOSFET devices each rated for 1.8 kW dissipation. This enhancement not only improves the overall robustness and efficiency of the amplifier but also ensures even greater linearity under demanding operating conditions. In essence, these upgraded MOSFETs deliver a superior balance of durability, headroom, and performance, making this model truly stand out as one of the most advanced and reliable linear amplifiers on the market today.

  • Double MOSFET with 1.8 KW dissipation each.

    Granting great robustness, efficiency and linearity.

  • The smallest in its class:

Built-in Power supply and Automatic Antenna Tuner.

Dimension: L 28, H 12, P 38 cm ( 11.02” W, 4.72” H, 14.96” D ) connector included. Approx. weight about 9,5 Kg 
            (20.9 lbs).

  •  The most technologically advanced in the world:

Two powerful CPUs are used.

             Over 30,000 lines of software, for performance that cannot be found together in any other amplifier.

  •  Fully automatic:

    Easy connection with all models "ICOM, YAESU, KENWOOD, TEN-TEC, FLEX-RADIO, ELECRAFT" for immediate management of the bands, tuner and antennas.

    Same performance with all makes and some homemade rigs.

    The operator only has to move the “Frequency Tuning Knob” of the transceiver.
  • Wide frequency coverage:

1.8 MHz to 50 MHz including WARCs.

              60 m band, where permitted.

  • Fully solid state:

    Solid 1.5 KW out, HF (+/- 0.5 dB), 50 MHz (+/- 0.8 dB).

    Switchable in MAX (full power), MID (1KW) or LOW (500 W), power selected according to the operator’s requirement or automatic for amplifier protection.

    No warmup time, immediately ready!

  • Automatic antenna tuner built-in:

Capable of matching up to 5:1 SWR on HF, and 2.5:1 SWR on 6 meters.

Capable of program controlling 4 aerials (SO239 connectors).

Program up to 2 aerials for each band.

Management of SteppIR / Ultrabeam aerials (tunable).

Also measures the SWR of the antenna and cable system.

Bands, aerials, tuning conditions are changed in 10 msec.

Bands, aerials and tuning conditions are managed so that in “STBY“, only the exciter is passed through to the output.

Max. attenuation 0.8 dB. ATU bypass capable.

  • SO2R

  • Two inputs available:

SO239 connectors.

  • High power gain (up to 15 dB):

             In “OPERATE“ the required drive power is automatically set with the ALC connection.

In “STANDBY“ the exciter is automatically reset to full power.

  • Very clean and low distortion output:

Spurious emissions FCC, CE, RCM (C-Tick) compliant.

3rd order distortion (two tone test) from -32 dB to -38 dB, -35 dB ( typ. ).

  • Input / Protections:

            50 ohm always perfectly matchedSWR always better than 1.2:1.

             Temperature, Voltage, Current, reflected PW, out PW, SWR, Vrf max on tuner, etc.

              are continuously monitored. The same protection is realized in two different ways:

             Via hardware circuits (HW) to assure great speed.

             Via software (SW), to assure great accuracy.

              Due to the sophisticated software, the transmit relay changeover is carried out with zero current on the contacts.  

              Protection against first spike.

  • Full break-in operation (QSK).


  • Quiet operation:

Linear management of the speed of the cooling fans of the heatsink.

             The amplifier develops a significant amount of heat that must be removed. Therefore, every precaution is taken
             to keep the fan noise at the lowest possible level.
             Fan noise is significantly lower than with tube type amplifiers.

  • Use:

            Full I.C.A.S. in SSB, CW, FT8. In FM the amplifier automatically switches to "MID" if for 15 sec. a continuous 
             signal is emitted in "MAX".

  • Switching power supply:

Continuously operable at inputs between 100 – 255 VAC, 47-63 Hz.

(100-120 VAC may cause slightly reduced output power).

PFC (Power Factor Correction).
