Unassigned 9 9-pin D-sub connector pin connections Theory of Operation The 12 Channel Bi-Directional Amplifier (BDA) operates in the iDEN Specialized Mobile Radio (SMR) band. The Downlink Band is 851-866 MHz and the Uplink is 806-821 MHz. Each iDEN Channel is 25KHz wide and the Transmit and Receive Frequencies are offset by 45MHz. Unlike a Broadband BDA, which would amplify the entire band, the user can select up to 12 individual 25 KHz channels to be amplified. This increases the repeater’s performance by eliminating power sharing with undesired SMR signals and also prevents unwanted amplification of competitor’s iDEN channels. The unit is divided into two basic sections-An RF Section (2 Duplexer Filters, RF Board, Two Power Amplifier boards) and a Digital Section (Digital Channelizer Board) The 15 MHz wideband RF from the Base Station Antenna (851-866MHz) is directed by the duplexer to the DL input of the RF board. It is then down converted to an IF of 63.5-77.5 MHz using a LO of 788.5 MHz. A wideband Automatic Level Control (ALC) keeps the signal at the required level. The 15MHz wideband IF input from 63.5-77.5 MHz is sent to the digital board where it is Sub-sampled by an A/D converter operating at 56 MHz. This 6.5 -21.5 MHz Digital Signal is then sent to three 4-Channel Digital Down Converter (DDC) Chips. Each channel on the chip is comprised of a Digital Mixer, Numerically controlled Oscillator (NCO) and a Digital Filter. A individual Channel is selected by setting the NCO to the Channel Frequency mixing the signal down to base band were it is filtered. This Filtered Digital output now goes to three 4-Channel Digital Up converter Chips (DUC). The Baseband signal is now mixed up to 6.5 -21.5 MHz by selecting the corresponding NCO frequency. This Digital output is converted to analog by a D/A converter. This Signal is sent back to the RF Board for Up-conversion. The 6.5 -21.5 MHz is mixed with 56 MHz LO and filtered yielding 63.5-77.5 MHz, which is then mixed with the 788.5 MHz LO producing the 851-866MHz. The 851-866MHz output from the RF board goes to the RF Power Amplifier and then is sent back out through the duplexer to the Service Antenna. The Power Amplif…

Electromagnetic Compatibility Spurious Emissions at Antenna Terminal Requirements Measurement Procedures:As required by 47 CFR 2.1051, spurious emissions at antenna terminal measurements were made at the RF output terminals using a 25-watt 30 dB attenuator and a Spectrum Analyzer. Set a 50.7 dB Reference Level Offset, RBW = 300 kHz and VBW = 1 MHz to Spectrum Analyzer. RBW was set to 300 kHz to improve the Spectrum Analyzer noise floor. The EUT was set to transmit two tones in the lowest of the operating frequency range. The iDEN signal generators was adjusted enough to produce maximum output power as specified in the owner’s manual. The Spectrum Analyzer was set to sweep 15 MHz to the 10 th harmonic of the fundamental. The Display Line was set to -13 dBm as the limit line. Plotted the Spurious Emissions graph. This process was repeatedly done at the highest channels and each end of operating frequency range for Uplink and Downlink. Measured Output Power of EUT: 3.55 Watts (PEP; Peak Envelope Power) Spur limit = Po - (43 + 10logPo); Po = 3.55 watts or 35.5 dBm 35.5dBm - (43 + 10log 3.55) = 35.5 dBm - (48.5 dB) = -13 dBm Results:Equipment complies with Section 2.1051 and 90.210.

Electromagnetic Compatibility Radiated Emissions Requirements Measurement Procedures:As required by 47 CFR 2.1053, field strength of radiated spurious measurements were made in accordance with the procedures of TIA/EIA-603-A-2001 "Land Mobile FM or PM Communications Equipment Measurement and Performance Standards". Radiated emission measurements were performed inside a 10 meter semi-anechoic chamber (equivalent to an Open Area Test Site). The distance between the EUT and the test antenna is 3 meter. The EUT RF ports was connected with a 1.2 meter SMA cable and terminated to 50 ohm load. The EUT was set to transmit in the middle of the operating frequency range. The iDEN signal generator was adjusted enough to produce maximum output power as specified in the owner’s manual. To capture the full power spurious emissions, maximized each frequency by rotating the turntable to 360E and varying the test antenna from 1 to 4 meter height. Once the maximized emission is found, recorded the reading in a tabular format. These steps were repeated with horizontal polarization, for Uplink and Downlink. Once all emissions are collected and recorded, replaced the EUT with a substitution antenna connected to a 1.5 meter 2.92 mm(K) cable and a signal generator. All test setup on the receiving side should be the same as it was when measuring the emissions of the EUT. Repeat all steps above except that the emissions will be compared with the signal generator’s amplitude. Record reading in a tabular format. The Radiated Spurious Emissions Limit is obtained by the following: Measured Output Power of EUT: 3.55 Watts (PEP; Peak Envelope Power) Spur limit = Po - (43 + 10logPo); Po = 3.55 watts or 35.5 dBm 35.5dBm - (43 + 10log 3.55) = 35.5 dBm - (48.5 dB) = -13 dBm Results:Equipment complies with Section 2.1053 and 90.210.

Technical review has been completed on the referenced application. Please respond to the following questions: 1. I note that the EUT also meets the definition of a pc peripheral, subject to either Class A Verification, Class B Certification, or DoC. The Part 15 data shows compliance with the Class B limits. Which form of authorization is sought for this digital portion of the EUT? I note that the test set up shown in the Part 15 test report does not meet the minimum system set up requirement of ANSI C63.4. The EUT is the only peipheral attached to the pc, while the test procedure reuires a minimum of 2 peripherals be present. 2. Please provide internal and external photos of the EUT. FYI: (a) Section 90.219(b) limits the ERP of the transmitter, and not the RF conducted power level, to 5W. This is incorrectly shown in the Results Section IIIA of the Part 90 test report. Please note that the addition of an antenna with gain greater than 1.5dBi will bring the EUT out of compliance. The authorization of the antenna takes place during the licensing phase. (b) Because Necessary Bandwidth calculations were not provided, the actual, measured occupied bandwidth of 17.6 kHz is used in the emission designator, and not the channel width of 25 kHz.

Hi Greg, I’m done with the internal/external photos and do you have access to METrak? If you do, here is the link. But if you don’t let me know and I’ll email you the photos. \\Santaclarafp\sc_user\EMI\Report\13538 RFS\Internal Photos For question #1, I think this should have been on 15.209 instead of 15.109. Does it still need to meet the minimum configuration under ANSI C63.4, even if it is suppose to be 15.209? Talked to client and the PC can be connected all of the time but it does not have to be. Mainly use to configure the EUT and to troubleshoot. If this is OK with you, I will ask the technical writer to update the report otherwise retest with minimum configuration under ANSI C63.4. I’ll update the report for the ERP with noted max antenna gain of 1.5dBi. Also the client is OK with 17.6kHz occupied BW instead of 25kHz. Do you want the Part 90 report after updating it? Thanks for the updates. Kerwinn

No, I do not have access to METrak from here- please email to me the internal and external photos. Actually, for this device, Section 15.109 is correct, as it covers the peripheral portion of the EUT. The transmitter portion is Part 90, so 15.209 does not apply. If the EUT can be operated while it is connected to a pc, then it meets the de…
