Theory Of Operation Trafcon TX3 Transmitter The TX3 transmitter uses a frequency-modulated crystal-locked PLL and operates between 2.2 and 10VDC at a current of 10 mA nominal. At 3V it delivers (nominally) 0dBm (1mW) RF output. The data to be transmitted flows through a 27 kHz low pass filter into the modulation circuit which, in turn, drives the PLL circuit. A buffer supplies final output amplification which flows into a bandpass filter to the antenna circuit.

Dettling Documentation Specialist Reviewed by: Michael Violette President Document 6679-01, Rev. 0 FCC ID: PTB50069 FCC Certification Test Report Washington Laboratories, Ltd August 2001 ii Abstract This report has been prepared on behalf of Trafcon Industries, Inc. to support the attached Application for Equipment Authorization. The test report and application are submitted for a Periodic Intentional Radiator under Part 15.249 of the FCC Rules and Regulations. This Federal Communication Commission (FCC) Certification Test Report documents the test configuration and test results for a Trafcon Industries, Inc. TX3 Transmitter. Testing was performed on an Open Area Test Site (OATS) of Washington Laboratories, Ltd, 7560 Lindbergh Drive, Gaithersburg, MD 20879. Site description and site attenuation data have been placed on file with the FCC's Sampling and Measurements Branch at the FCC laboratory in Columbia, MD. Washington Laboratories, Ltd. has been accepted by the FCC and approved by NIST NVLAP (NVLAP Lab Code: 200066-0) as an independent FCC test laboratory. The Trafcon Industries, Inc. TX3 Transmitter complies with the limits for a Periodic Intentional Radiator device under Part 15.249 of the FCC Rules and Regulations.
