It is with great satisfaction that M
2
now offers a true breakthrough in high power VHF amplifiers. Our goal has always
been to offer the most carefully designed, high performance antenna products. Now we offer the same high performance
in VHF amplifiers. The 6M-1K2 and the 2M-1K2 utilize the new Freescale™ LD MOS FET (MRFE6VP6IK25H), a single
device specified to produce 1.25 kW with as little as 3 watts of drive from HF to 600 MHz. This is amazing in itself, but
adding its inherent stability driving that power into a 65:1 mismatch is equally incredible. It can do all this at efficiencies
well above 60%!
YOU CAN SEE WHY WE ARE EXCITED!
Here is where M
2
comes in. We wanted to make it small and we did; 6 x 7.125 x 13.5 inches (152 x 181 x 343 mm) so it
will fit in a suitcase. We wanted it to be light and it is at just 13 lbs (5.9 kg). The optional integrated 2400 watt switching
power supply adds only another 7.5 lbs to this incredible package that travels easily at 20.5 lbs (9.3 kg). Additionally, the
power supply may be purchased as a separate, standalone accessory.
Now, at home in your shack you won’t need that big steel rack any more. All you need is a small desktop or shelf to hold
your QRO (high power) VHF amplifier.
Above all we made this amplifier easy to understand and operate. The photo below shows the model with the amplifier
and the power supply integrated together (7.125” wide, 9” high 14” deep).
INTRODUCTION
By now you may realize that there is a lot more in this amplifier
package than just a 1.25 kW LDMOSFET.
What you can’t see in pictures is listed proudly below:

A complete and accurate high power VSWR bridge.
 Regulator PC board with high wattage power resistors and
two voltage regulators.
 Medium power input power coaxial relay.
 High power, high speed vacuum relay easily capable of
handling full output power.
 Monitoring via high accuracy DC current and temperature
monitoring devices.
 Sophisticated output RF filter reducing spurious harmonics
to exceed FCC regulations.
 Quiet fan on the bottom cools miniature RF tank and filter
components.
 50 or 100 watt input attenuator that reduces your input
power to safe drive levels.
