                                                              NX5DSSR-250C


2) MPE estimate has 57 dBm = 500 W. Please explain if/how this
corresponds to 10kW output power on Form731.

As described on page 5 (bottom right hand corner of page) of our submission,
the transmitter is composed of a power combiner that sums a variable quantity
of 125 watt RF power amplifiers to generate the coherent output RF signal of
a desired level. This is a pulsed radar system operating at a maximum of 5%
duty Cycle. The PULSAR RF Power modules are designed to be power added to
“optionally” produce the following output RF power levels:

                  PULSAR VARIANT MODEL NUMBERS
           Nomenclature                    RF Peak Pulse Power
Pulsar                           Standard, 250 Watts minimum
Pulsar–1                         Optional, 500 Watts typical
Pulsar-2                         Optional, 1000 Watts typical
Pulsar-3                         Optional, 2000 Watts typical
Pulsar-4                         Optional, 5000 Watts typical
Pulsar-5                         Optional, 10,000 Watts typical

Thus, the PULSAR-5 operating a 10,000 watts peak power would produce an
average power of 27dBW or 57dBM. Since the radiation hazard potential is
calculated in milliWatts/cm^2, the formula requires the transmitter “average
power” to be inserted in milliWatts, thus 57dBM would be the worst case for
average power.
