1 KW Solid State Fully Automatic Linear Amplifier

RF SOLUTIONS is the authorised dealer for Australia/New Zealand

The smallest in the world

Built-in power supply and automatic antenna tuner.
Dimensions: W 28cm, H 14cm, D 32cm (connectors included).
Weight: Approximately 20kg

The most technologically advanced in the world

Two CPUs are used, one of which is dedicated to the transceiver interface requirements (CAT).
Pi-L output circuit.
Over 13,000 lines of software for performance that cannot be found in any other amplifier.

Fully automatic

Easy connection with all models ICOM, YAESU, KENWOOD, TEN-TEC, FlexRadio, ELECRAFT, for immediate management of the bands, tuner and antennas.
Same performance with all makes or homemade rigs.
The operator only has to turn the “Frequency tuning knob” on the transceiver!!!

Wide frequency coverage

1.8 MHz to 50 MHz – all amateur bands including WARC bands.

Full solid state

1 KW pep SSB output; 900 W pep CW output (typically); 700 W pep output (typically) on 50 MHz.
FULL / HALF power selected according to the operator SSB/CW power requirement, for digital modes and for linear protection (automatic).
No heating time, immediately ready!
Virtually limitless life of the amplification devices (MOSFETs).

Automatic antenna tuner built-in!

Capable of matching 3:1 SWR on HF, and 2.5:1 SWR on 6 meters.
Capable of programmable switching of 4 antennas (SO239 connectors).
Up to two antennas for the same band.
Bands, antennas, tuning conditions are changed in 10 msec.
Bands, antennas and tuning conditions are managed also in “STBY” to support the exciter only.


Two radio inputs available

SO239 connectors.

High power gain (up to 15 dB)

In “OPERATE” the required drive power is automatically set with an ALC connection.
In “STANDBY” the exciter is then automatically reset to full power.

Very clean and low distortion output!

Spurious emissions less than -50 dB (50 MHz – 60 dB).
3rd order distortion (two tone test) 36 dB typically.

Input 50 ohm always perfectly matched

SWR less than 1.2:1.

Fully protected

Temperature, over voltage, over current, SWR, reflected power, max RF tuner voltage, over-drive, Amp.
The correct parameters are continuously monitored.
The same protections are realised in two different ways:

  • Via hardware (HW) to ensure great speed.
  • Via software (SW) to ensure great accuracy.

Thanks to the SW, transmit relay changeover is carried out with zero current at the contacts.

Full break-in operation (QSK)

Normal / contest operation to optimise the performance!

Very quiet operation!

Seven quiet three-speed cooling fans:

  • 150 CFM maximum total air flow.

Temperature thresholds for speed change:

  • 40 degrees C, 70 degrees C, and 83 degrees C (normal mode).
  • 60 degrees C, and 75 degrees C (contest mode).

Noise level:

  • 39 dBa at maximum blower speed.

Continuous use

“FULL” mode: SSB unlimited, key down 2 minutes.
“HALF” mode: SSB unlimited, key down 5 minutes.

Regulated power supply, input 230 / 215 / 200 / 115 / 100 Vac

With all input voltages the output power does not change.
A well designed grain-oriented, tape-wound toroidal transformer reduces magnetic fields around the amplifier.

The linear can be switched ON / OFF automatically when switching ON / OFF the exciter

A large LCD screen displays a wide range of information

W pep out, V pa, I pa, W pep reflected, power gain, temperature degrees in Celsius, SWR, input setting, CAT setting, band and other indicators including an alarms log.

Easy to operate

Powerful software gives you a user-friendly unit.

RS 232 port for PC control

Software is supplied to remotely control the linear front panel.
With a proper protocol it is possible to use this port not only as a remote control, but also as a CAT port (useful to link the linear with any customer application).

Easy transportation

A sturdy carry-bag is supplied for QSY, FIELD DAY, DX EXPEDITIONS etc.

Certifications: RCM (C-Tick), CE, FCC

Specifications are subject to change without notice
