TRL TECHNOLOGIES, INC.FCC ID: OEUPA936M125W PAGE 1 OF 2 OPERATIONAL DESCRIPTION 1. DESCRIPTION a) Individual Stages The Power Amplifier is divided into the following sections: • Splitter Stage: includes DC supply, display LEDs, driver, temperature sensor and 2-way hybrid splitter. • Amplification Stage: consists of two 100W final amplifier modules. • Combiner Stage: consists of VSWR monitor circuitry, hybrid combiner, circulator and low pass filter. b) Overall Lineup The input RF is padded down and fed to a MMIC gain block before getting amplified by a RF power transistor that has adjustable gain. This intermediate amplified RF signal goes through a 2-way hybrid splitter and then amplified again by 2 final PA modules. The resultant signals are recombined and routed to a circulator and then a low pass filter before going out to the PA’s output port. A temperature sensor locating on the driver board monitors the PA’s heat sink temperature. Temp LED display will turn on when the heat sink temperature is exceeded 65°C. The PA’s Output VSWR level is monitored at the circulator load. VSWR LED display will turn on when the output VSWR is approximately 3:1.

The tests were performed for TRL Technologies of Hoffman Estates, Illinois. 1.2 PURPOSE: The test series was performed to determine if the test item meets the occupied bandwidth, spurious emissions at antenna terminals and spurious radiated emissions requirements of the FCC Part 90 for 928-944MHz Amplifiers. 1.3 DEVIATIONS, ADDITIONS AND EXCLUSIONS: There were no deviations, additions to, or exclusions from the test specification during this test series. 1.4 APPLICABLE DOCUMENTS: The following documents of the exact issue designated form part of this document to the extent specified herein: -Federal Communications Commission "Code of Federal Regulations", Title 47, Part 90 - Federal Communications Commission "Code of Federal Regulations", Title 47, Part 2 - ANSI C63.4-1992, "American National Standard for Methods of Measurement of Radio- Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz" 1.5 SUBCONTRACTOR IDENTIFICATION: This series of tests was performed by the Elite Electronic Engineering Company, radio interference consultants of Downers Grove, Illinois. 2.0 TEST ITEM SETUP AND OPERATION: 2.1 SETUP: The test item was powered with 26VDC from a power supply. ENGINEERING TEST REPORT NO. 21661 2 An input signal from a Hewlett Packard model 8648C signal generator (used in conjunction with a Hewlett Packard 8111A function generator) was fed into a Ophir model GRF5064 RF power amplifier. The 35 Watt output of the Ophir amplifier was used to drive the test item. The level of the input signal was adjusted until the power output was at the maximum level. 2.2 MODULATION: The test signal was frequency modulated (FM) with a 3.5 kHz audio tone at 14.0kHz deviation which is a typical modulation for 928-944MHz radio services. 2.3 FREQUENCY SELECTION: A single frequency in the center of the frequency band was selected. The specific test frequencies are designated as follows: ModulationFrequency Type (MHz) FM936.0 3.0 TEST EQUIPMENT: A list of the test equipment used can be found on Table I. All equipment was calibrated per the instruction manuals supplied by the manufacturer. 4.0 REQUIREMENTS, PROCEDURES AND RESULTS: 4.1 OCCUPIED BANDWIDTH MEASUREMENTS: 4.1.1 REQUIREMENTS: In accordance with Paragraph 90.209(b)(5), the maximum authorized bandwidth shall be 20kHz for operations in the bands 902MHz to 928MHz. In accordance with paragraph 90.210(b), the peak power of any emission shall be attenuated below the unmodulated carrier power (P) in accordance with the following schedule: (1)On any frequency removed from the assigned frequency by more than 50 percent but not more than 100 percent of the authorized bandwidth: At least 25 dB. ENGINEERING TEST REPORT NO. 21661 3 (2)On any frequency removed from the assigned frequency by more than 100 percent but not more than 250 percent of the authorized bandwidth: At least 35 dB. (3)On any frequency removed from the assigned frequency by more than 250 percent: At least 43 + 10log (P) dB. 4.1.2 PROCEDURES: (a)The input signal was set to 936.0MHz. The input signal level was adjusted to provide the maximum level at the test item output. (b)The input signal was FM modulated. (c)A spectrum analyzer was connected to the output of the test item. With a bandwidth of the spectrum analyzer set to 1kHz, the output of the test item was measured and recorded. (d)The input signal from the signal generator was measured with the spectrum analyzer and recorded over the same frequency range. 4.1.3 RESULTS: The plots of the occupied bandwidth measured with the FM modulation of the carrier are presented on data pages 101 through 103. The limits, shown on the plots, are referenced to the power measured from the unmodulated carrier. As can be seen from the data, the test item output met the occupied bandwidth requirements with the FM modulation of the carrier. The sideband emissions measured at the test item output were similar to the sideband emissions me…
