OM -1 Transmitter

Typical Overmodulated Pulse output of the OM-1

                                   250,000 Hz output signal                                             500,000 Hz output signal

The OM-1 is an entirely unique form of pulsed radio transmitter. Fully FCC approved as a Part 18 ISM transmitter, the OM-1 uses overmodulation to create it's pulse. It works best up to about 200 KHz, but will modulate to beyond 500 KHz.   Overmodulation is superior to gated continuous carrier as the energy of the demodulated wave is many times higher on a watt per watt basis.

If you already have an overmodulated CB based transmitter driving your pulsed EM field system, the OM-1 is a direct  replacement. The decreased rise and fall times of the pulse envelope, coupled with the increased modulated power levels will make large differences in your present system.  

Caution: Most amplifiers will not tolerate usage above 30 KHz. To use frequencies above 30 KHz, will most likely destroy your present amplifier. At this time, only the Part 18 ISM amplifier provided by Plasma Sonics is capable of utilizing the full frequency capability of the the OM-1. 

OM-1 APPLICATIONS:

1. Driver for RF powered Lasers – May be used for cutting and welding of many different materials such as plastic and metals.
2. Gas plasma generation – Thermal and Non Thermal. RF excited gas plasmas are useful for electronics manufacturing and sterilization.
3. RF induction welders.
4. RF excited, UV emitting plasma tube for sterilization/decontamination of large surface areas.
5. RF excited gas plasma tubes.
6. Over the horizon radar using Zennick waves generated by round plasma tubes.

Please note that many of these applications will require significant amplification of the OM-1's power.

SPECIFICATIONS:

Frequency: Crystal controlled at 27.125 MHz

Un-modulated Power - 3.8 watts typical. If you decide to use an amplifier with the OM-1, get one that will drive to maximum power with 4 to 5 watts carrier input power. 

Modulated Power at 10 KHz - 32 watts PEP into a 50 ohm load. This high modulated power level will not damage an amplifier rated for 3 to 5 watt input power. It may cause the amplifier to run a bit hotter than normal, extra fan cooling may be necessary. 

Rise and Fall Times of Pulse Envelope - Typical 1.1 microsecond

4 pin plug allows for remote control, or computerized control. Standard Uniden pin arrangement.

Power requirements - 3.5 amperes at 13.8 volts D.C.

Square Wave duty cycle - typical 50% -  Rise and Fall times of the square wave generator must be better than that of the OM-1 for optimal operation. 

Usage Duty Cycle -  100% .  The OM-1 is designed for continuous operation at full power. 

Due to the high degree of overmodulation, this transmitter is useless for voice communication.
