TRL TECHNOLOGIES, INC.FCC ID: OEUPA882M180WS2 Page 1 of 4 OPERATIONAL DESCRIPTION 1. DESCRIPTION a) Individual Stages The Power Amplifier is divided into the following sections: • Splitter / Driver Stage: divides into DC and RF sections. DC section covers DC supply regulation, display LEDs. RF section includes attenuators, RF splitters, RF input detector circuit and driver amplification. • Amplification Stage: consists of two final amplifier pallets. • Combiner Stage: consists of power monitor circuitries, combiner, circulator and low pass filter. • PA Control: contains input signals, microprocessor and output signals sections. b) Overall Lineup The RF input is attenuated, split and routed to an input-power-detection circuit and a variable attenuator. The signal is further attenuated, amplified and passed to another splitter. The result is then fed to 2 final power amplifier pallets, combined and routed to a circulator and then a low pass filter before going out to the PA’s output port. There are sensors and couplers placed through out the PA to monitor the PA’s input level, forward and reflected power output levels, as well as the ambient and heat sink temperature. These sensor and coupler voltages are utilized by the on-board HC11 microprocessor to provide various PA alarm and protection. 2. FEATURES The 180W Power Series II PA provides numerous alarm monitor and protection features. a) Fold Back Mode The PA will go to the Fold Back Mode and reduce its power by 3dB (90W) when • Load VSWR is between 2:1 to 3:1 • Ambient temperature is between 45 to 60°C b) Alarm Indicators AlarmsLED StatusCondition DC PowerSolid Green LED Flashing Off Between 25V-28V Between 22-25V or 28V-30V Less than 22V or Greater than 30V or No power at all TX OnSolid Green LED Off PA is transmitting PA is not transmitting RF InputSolid Red LED Flashing Off No input power Over/Under limit specification Input power is within limit High VSWRSolid Red LED Off Greater than 2:1 VSWR No alarm Over TempSolid Red LED Flashing Off Ambient Temp is greater than 60°C or Heat sink Temp is greater than 90°C Ambient Temp is between 45 to 60°C No alarm Table 1.

An input signal from a Hewlett Packard model 8648C signal generator (used in conjunction with a Hewlett Packard 8111A function generator) was fed into an Ophir model GRF5064 RF power amplifier. The 15 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 6.5 kHz audio tone at 12.0kHz deviation which is a typical modulation for 869-894MHz 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: Modulation Frequency Type (MHz)_____ FM 881.5 3.0 TEST EOUIPMENT: A list of the test equipment used can be found on Table 1. 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 22.917(b), the peak power of any emission shall be attenuated below the 2 TRL TECHNOLOGIES, INC.FCC ID: OEUPA882M180WS2 ENGINEERING TEST REPORT NO. 22443 Unmodulated carrier power(P)in accordance with the following schedule: (1)On any frequency removed from the carrier frequency by more than 20kHz but not more than 45kHz: At least 26 dB. (2)On any frequency removed from the carrier frequency by more than 45kHz, up to the first multiple of the carrier frequency: at least 60dB or 43 + 10log (P) dB, whichever is the lesser attenuation. 4.1.2 PROCEDURES: (a) The input signal was set to 881.5MHz. 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 driving amplifier 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 105.

TRL TECHNOLOGIES, INC.FCC ID: OEUPA882M180WS2 This is to reply to your email correspondence reference number 14801, 731 reference number EA96680, FCC ID OEUPA882M180WS2 1. We are requesting that the spurious, radiated, conducted and occupied bandwidth tests at 20W input to be waived due to the fact that the PA is designed so that the input RF level to the driver gain stage always remains constant. In other words, the PA’s overall RF characteristic will not change with the input level’s variation. As show in block diagram below, the variable RF signal at the PA input is always padded down to a fixed level before feeding to AMP1. This is done using a combination of resistive attenuator (1), voltage variable attenuator (2) and resistive network attenuator (3). The resistive attenuator (1) is varied from 5, 10, 15 or 20dB depending on the customer’s input level. The voltage variable attenuator (2), which controlled by the microprocessor, is then used to fine tune the RF signal to a fixed level expected at AMP1 input. The result is the same RF signal will be passing through the entire gain lineup every time, independence of the PA input. 2. A copy of the occupied bandwidth with digital input file is uploaded as Test Report: occupied bandwidth data. Note that the same copy was also uploaded earlier under Add Attachment as part of the submitted data. 3. Intermodulation test is not required for the PA since it is operated as a single channel system. TRL TECHNOLOGIES, INC.
