ALS-1406, AMERITRON 1200WATT, 1.5-54Mhz, LDMOS Solid State Amplifier with 220 VAC Switching Power Supply

.Fully FCC certified (FCC certification # : HO82WUALS1406 )

Ultra reliable LDMOS technology has 20 years of proven widespread use in extremely high SWR environments -- commercial broadcast transmitter and industrial applications like plasma generators, lasers and MRIs. The LDMOS transistor used in ALS-1406 is designed to handle SWR up to 65:1. It can withstand almost any load from a short to an open circuit!!!.

Benefits of LDMOS transistor used in the ALS-1406:

Very good linearity--gives you clean SSB, CW and digital signals

  •  Superior efficiency-- gives you more power output for less power consumed
  • No catastrophic overheating because of thermal runaway--protects against sudden transistor failure
  • Excellent structural thermal conductivity--readily channels unwanted heat out and allows significantly higher continuous RF power level

Ameritron HF+6 1200W Solid State Amplifier 1.5-54 MHz . . . 1200 Watts PEP Output, Instant Automatic band switching, no tuning, no warm-up, SWR protected, Quiet Variable-Speed Cooling . . . PEP FWD/REF Metering...PA Balance /ALC Metering and LED Indicator . . . Front Panel Band/Error LEDs . . . more!

ALS-1406 reliability is insured by using two NXP M/RFE6VP5600H LDMOS transistors. They are mounted on the dual heavy duty heat sink and properly arranged to spread out the heat over a large surface. 

The ALS-1406 RF deck operates at 50 Volts for efficient, low distortion linear RF power service. It’s cooled by a whisper quiet cooling fan. Fan speed is regulated by temperature sensors, assuring minimum noise for adequate cooling.

            1200 Watts SSB Output Power Covers 1.5-54 MHz (HF+ 6Meters!)

ALS-1406 runs up to 1200 Watts of clean SSB output power (just 100 Watts drive gives you the full rated 1200 Watts output) for continuous coverage between 1.5-54 MHz. 10/12 Meters is already included.

Operator-friendly layout fits nearly any station configuration. The attractive desktop amplifier unit weighs only 22 pounds. Compact 10W x 6 1/2H x 18 1/2D inches.

SWR Protection prevents amplifier damage if you switch to a wrong band, use the wrong antenna or have a high SWR. Over-power protection enables if output forward power or reflected power exceeds a safe level.

Output power is automatically reduced to prevent amplifier damage by controlling ALC to exciter.

LED-illuminated Cross-Needle SWR/Wattmeter lets you read SWR, forward and reflected peak power simultaneously. You also get ALC, SWR, PA balance and current metering with LED back-light. An Operate/Standby switch lets you run “barefoot”, but you can instantly switch to full power if needed.

                                                        Front-panel ALC control!

This exclusive Ameritron feature lets you adjust output power on the convenient front panel display. You get front panel operation, band and error LED indicators like reflected power and bandswitch errors.

                                                      Automatic Band Switching!

Put your amplifier and power supply out-of-the-way! Control your amplifier directly from your rig!

ALS-1406 automatic band switching capability reads band data from your transceiver and automatically changes bands as you make adjustments on your transceiver. An optional interface cable is required for your particular radio. See DB cable section.
                                                     Clean, Modular Construction

Unlike other solid state amplifier designs that are packed so tightly they are unserviceable, Ameritron’s ALS-1406 amplifier construction is super-clean with easy-service modular construction.

                                                     ALS-1406 Power Supply

The ALS-1406 is powered by a 50 VDC switching power supply. Comes with a pre-wired cable to plug into the ALS-1406.

This hash-free fully regulated switiching power supply is only 12 lbs. and measures a compact 10W x 6 1/2H x 9 1/2D inches. It can be placed conveniently out-of-the-way at your operating station. Output is 50 VDC at 50 Amps to the ALS-1406. Wired for 220 VAC, selectable to 110 VAC. Draws less than 25Amps at 110 VAC; 12A@220 VAC.
