SA8MARKII-CII-DMDPower Amplifier

Rev 2.0 6/6/04 If you have determined that the White module (U2 (STM901-30) driving the Final PA has failed... MARKII kit contains the following: 1 1ea PA assembly board 2 1ea Aluminum Spacer w/ four holes 3 4ea 3/16 #4/40 screws (for Q2 on MARK II) 4 2ea ½” #4 metric torq screws (for fastening Mark II Board & Spacer) 5 1ea FCC Label for placement on exterior of PA housing Please see B3521R3A.pdf or 19D902757G5 Mastr III PA schematic for the proper installation of this replacement module. The fan kit 188D6127G1 assembly supplied from MA/Com is required for this module for warranty to be valid. The PA will exceed heat tolerance & fail without this fan kit. Disconnect ALL power & control cable from the Mastr III Power Supply Remove U2 (STM901-30) from Power Amplifier Board A1...being careful to not damage the lands on the remaining board. Disconnect P101 from J101. (the small gold connector from the BNC input from the MIII exciter) This aids in the installation of the MARK II module. Apply heat sink compound “sparingly” to the bottom of the Aluminum Spacer Plate of the MARKII RF board. It has been proven that less is better with regards to heat sink compound. Apply only a slight amount, but sufficient to cover the surface. Align spacer plate so both holes in the circuit board of the MARK II module align for mounting. Slowly screw down each side until snug (No more than 1ft/lbs torque). Place spacer & Module into position where the U2 (STM901-30) module was previously. Mount assembly using the 4 ea. #4-40 screws. Secure all screws snug (No more than 1ft/lbs torque). Insert the module under the small hard-line coax P 101 into position & mount using all 4 screws. Be certain no excessive heat sink compound is across any connections Solder the 5 connections from the MARK II module to the pins on the Power Amp using proper RF practice. Stripped Cat5 cable lead cut to about 400 mils can be used to make your leads. Use the following U2 pin connections with the MARKKII PA. U2 PIN 12 11 6 5 2 1 MARK II RFout VDD2(A+) VG2 VDD1(A+) VG1 RFin | | | | | | It is suggested to make your pin leads bent on a 45 degree angle and soldered in the following manner making sure leads which protrude off board do not touch its own ground plane. Ex. Rfout(MarkII) Rfout(G5 Card) After inspecting that all leads are secure and all flux, etc. is cleaned off board, you are now ready for testing. Reconnect P101 to J101 Turn R1, R2, R3, R4, R204, and R48 fully counterclockwise (down approx 20 turns) (R2, & R3 will now have no effect) With all power & control cables disconnected & digital ohmmeter negative on ground : Connect 28VDC supply only (no control or drive cables) Turn 28VDC supply on (do not transmit yet ) Set Digital power PA pot on Mastr III at 97 Shut off Power Supply & connect all cables from PA to Mastr III Turn Supply back on Adjust R48 while monitoring base of Q5 (the Final) to .675 VDC Now apply PTT (Transmit) (Note: RF Power level is low...This is normal at this point of procedure!) While monitoring TP1, you should not have any control voltage. While PTT is on, slowly adjust R204 clockwise until a voltage appears on TP1 (about 0.200 VDC). Now, you have activated the knee voltage on the 22Volt regulator switch. This is needed to bias up the transistors with small signal conditions to settle in without a load, since LDMOS is very sensitive to break in voltage. Adjust R1 slowly (over at least a 20 second period) to 4.7VDC (approx 10 turns) Adjust R4 slowly (over at least a 20 second period) to 4.8VDC (approx 10 turns) Adjust R204 to approx 11 Amps or 100 watts while monitoring current and power. At this point, the amp is ready to be fielded. Place cover back on unit and remember, any digital pot setting above 95 will yield upward of 120 Watts and is not recommended nor warrentied if users go above 100 Watts of operation. Installation of Identifying Label FCC and Industry Canada Regulations require the installation of the label provided prior to operating the unit. Unit is ready for operation.

Response to ATCB Comments FCC ID: SA8MARKII-CII-DMD 1 Washington Laboratories, Ltd. 7560 LINDBERGH DRIVE GAITHERSBURG, MD 20879 (301) 417 – 0220 FAX # (301) 417 - 9069 September 23, 2004 Mr. Dennis Ward American Telecommunications Certification Body Inc. 6731 Whittier Ave McLean, VA 22101 RE: Comments of September 17, 2004 APPLICATION: SA8MARKII-CII-DMD Communications International, Inc. Dear Mr. Ward: Below are the comments that you have provided regarding the application for certification referenced above. Our responses to those comments are in bold italic. Many responses refer you to additional exhibit(s) which has been uploaded to the application folder at the ATCB website. Thank you for your attention. Please feel free to contact us for any additional information that you may require. Regards, Gregory M. Snyder Chief EMC Engineer, Wireless/Telco Services Manager Brian J. Dettling Documentation Specialist WLL Project: 8188 1) Please note that the internal photos do not appear to show all of the boards or components. R. The exhibit has been upgraded to show all boards. Please see “Mark II Internal Photos Revised.pdf”. 2) Please provide internal photos showing tops and bottoms of all boards in the amplifier. Please note that the FCC ID label states, “THIS UNIT CONTAINS Communications International, Inc. Mark II Upgrade Kit FCC ID: SA8MARKII-CII-DMD”. Please note that the FCC identifier is to be on the device certified. This statement would indicate that the FCC ID’s device is inside the product. Please explain and please show where on the FCC ID’s device the FCC ID label is to be placed and please provide a sample of the actual label that is to be on the FCC ID’s device. If the product shown in the FCC ID label exhibit is the actual device, please clarify the term “contains”. Response to ATCB Comments FCC ID: SA8MARKII-CII-DMD 2 R. The phrase “This Unit Contains” has been removed from the label. Please see exhibits “Mark II Label and Location Rev 1.pdf” and “Mark II User Manual Rev 1.pdf”. 3) Please provide a 731 which clearly identifies the emissions designators to which this device operates. (i.e. your report states ‘digital modulation’ and ‘analog’ modulation, but does not clearly identify what emissions designator is used.) Please clarify. Please clearly identify these emissions designators in the report as well (i.e. F1D, F3E, GXW, G7W etc). R. As the Mark II upgrade kit is used with the MASTR III Base Station (M/A-COM FCC ID: OWDTR- 329-A2), the emission designations will be the same as for the MASTR III System (i.e. F3E, F1D, F1E, F2D and F2B). Please see exhibit “Mark II Application Form - 731 Revised.pdf”. Additionally, the test report has been revised to list these designators in Table 1. Please see exhibit “Mark II Test Report Rev 1.pdf”. 4) Please note that the plots provided in the report are not clear. It is not possible to clearly identify what the plot is saying. Please provide plots that are clear. R. The graphics have been reworked in the revised test report and the PDF conversion settings have been upgraded to allow improved clarity of the plots. 5) Please provide intermodulation test data for this amplifier. Alternately please explain why intermodulation tests are not required. In the case of the later, please give justification for this position. R. Intermodulation tests are not required as this amplifier is controlled by the MASTR III Base Station and is only connected to the single transmit output of the Base Station. Additional documentation (Maintenance Manual for the 110 Watt Power Amplifier with the MASTR III) has been provided for reference and to better explain the interface with the MASTR III Base Station. Please see exhibit “LBI-39127 Maintenance Manual.pdf”. 6) Please provide an MPE report or explain why an MPE report is not needed. Please provide justification if the latter. R. This amplifier is intended for use at fixed base station sites only. The antenna used for the base station transmitter will be fixed-mounted on outdoor permanent structures. As stated in the MASTR III Grant the RF exposure compliance is addressed at the time of licensing, as required by the responsible FCC Bureau(s), including antenna co- location requirements of §1.1307(b)(3).
