November 9, 1999 Federal Communications Commission Office of Engineering Technology 7435 Oakland Mills Road Columbia Maryland 21046 Gentlemen: In applying for certification (type acceptance) for the Feed Forward Power Amplifier FFPA8689-120, and Combiner Shelf Assembly HPC8689-400, MPD requests that certain items be withheld from public inspection. This request is made in accordance with FCC section 0.459 (a) & (b). The documentation submitted for review with the request for type certification includes trade secrets, which if made publicly available would seriously injure MPD’s competitive advantage. MPD’s competition could gain advantage by studying these documents and acquire the unique design features of our amplifier. These unique design features are MPD’s trade secrets that allow MPD to competitively produce an amplifier with respect to the number of carriers, modulation standards, and power level(s), etc.,. The documents that MPD requests confidentiality (Non-disclosure) are: Enclosure Two &Three:Specific description of circuits in the Feed Forward Power Amplifier and Shelf Assembly. Enclosure Four:Detailed circuit diagrams and assembly drawings in the Feed Forward Power Amplifier and Shelf Assembly. Regards, Murat Ero n, Ph.D., Director of Engineering Wireless Products

The unit can be operated as a stand-alone device or installed in a distribution rack that allows for multiple amplifiers to be installed for greater power. The unit under test has a maximum output power of 120 watts. 1.1 Device Configuration During Test The unit under test was configured and operated by the manufacturer throughout the tests. The unit was configured to produce a maximum output for all signaling techniques. The following is a list of available signaling techniques: CW, TDMA, CDMA, 2 FSK, and modulated CW Project Number: 99ME45100Issue Date: November 19, 1999 File Number: NC3932 Model: FFPA-8689-120 (Amplifier) and HPC8689-400 (Shelf) FCC ID: MCD FFPA8689-120 Comparison of Amplifier Output to Amplifier Input for Distortion The amplifier, which was tested both installed in a distribution rack and as a stand-alone device, was injected with a CW signal at the fundamental frequency. The input was adjusted to produce and output of 50.8dBm when the unit was tested as a stand-alone amplifier and 50dBm when tested in the shelf. These values produced the maximum power at the amplifiers output connector. Prior to injecting the signal into the amplifier, the input was examined and printed for comparison purposes. The signal was then injected into the amplifier and the output was analyzed to detect any distortion produced by the amplifier. The amplifier, which was tested both installed in a distribution rack and as a stand-alone device, was injected with a CW signal modulated with 1-kHz with a deviation of 5kHz at the fundamental frequency. . The input was adjusted to produce and output of 50.8dBm when the unit was tested as a stand-alone amplifier and 50dBm when tested in the shelf.
