Raytheon Request for FCC Special Temporary Authorization
STA File Number: 0580-EX-ST-2017
Date: 5/5/2017

Purpose of Operation:
The purpose of this testing is to measure X-band propagation loss over land from the Raytheon test
site at 50 Bush Hill Road, Pelham NH, to two or more receiver sites of interest.

Technical Synopsis:
 Spectrum needed: 8.5 – 8.99 GHz and 9.21 – 10 GHz
 Power levels requested: 419 kW peak ERP
 Location of use: 50 Bush Hill Rd., Pelham, NH
 Direction of radiation: 177.4, 183.3, 44.5 or 194.5 degrees from True North Azimuth;
0.0 degrees Elevation
 Stop buzzer contacts: Thomas Lulsdorf (cell 978-815-9514), Karen Dyberg (cell 508-450-
9236)

STA Explanation:
This Special Temporary Authority (STA) is necessary because X-Band transmission is required in
order to perform measurements of propagation loss in the directions of interest. Measurement under
typical conditions is required because the land in the directions of interest is too complex and
variable for reliable modeling of the over land propagation loss. The next stage of developmental
testing is dependent on the results of this experiment and a speedy result is required to maintain
schedule.

Test Summary:
An X-band signal will be transmitted from a linearly polarized horn antenna in one of four directions
of interest. Receiving equipment will be set up at the sites of interest to measure power received.
The measured propagation loss overland can be determined from the power transmitted, power
received and other known equipment parameters.

RF Hazard Calculations and Site Safety Measures:
Initial calculations show that general public exposure limits will be reached at a 118 meter distance
and occupational exposure limits at 17 meter, using peak power levels and formula (7) from FCC
OET Bulletin 65 “Evaluating Compliance with FCC Guidelines for Human Exposure to
Radiofrequency Electromagnetic Fields”, dated August 1997. Accounting for duty cycle, the
distance to meet the general public limit drops to 53 meters, and 8 meters for occupational. To avoid
overexposure of authorized site personnel, an exclusion zone will be marked during transmit
operations and an RF safety plan will be in place.

Equipment Information:
Synthesized signal generator (Tektronix AWG70001A).
TWT Amplifier (Applied Systems Engineering model 174X)

Experimental (Y/N): N

For each frequency band:
RF output at the transmitter terminals:
2172.7 Watts peak maximum

Effective radiated power from the antenna (if pulsed emission, specify peak power):
The effective radiated power from the antenna, including antenna transmit gain and front-end losses,
is ≤ 418.943 kW (peak power). Used the highest gain of 3 possible antennas.

Power * gain = EIRP, gain ≤ 25 dBi, EIRP ≤ 687068 W

Less than 0.1 %

List each type of emission separately for each frequency (basically list the waveforms and
emission designators)
See information under Necessary Bandwidth below.

Necessary bandwidth (Bn). Explain how determined. See NTIA Manual Annex J.
Waveforms are intended to simulate pulsed linear FM radar waveforms. Therefore the formula
Bn = 1.79/sqrt(t*tr) + 2*Bc from Annex J for FM pulse radars is used.
