Upon completion of integration, and prior to commencing transmitter operation, an RF output power measurement shall be made to ensure that the output power does not exceed 5W. c. The following Maximum Permissible Exposure (MPE) limitations assume a single transmitter, with a maximum antenna gain of 2.5dBi, using vertical polarization. Controlled Exposure MPE limitations are met at a distance of 12cm from the radiating element, and a 20cm separation is recommended. Users shall be instructed to maintain this clearance when the transmitter is active. Uncontrolled Exposure limitations are met at a separation distance of 27cm. Device integrators are responsible for MPE compliance of the installed environment. 4) This device shall be installed and maintained to provide a maximum of 5W of transmitter RF output power. Production tolerances and allowable adjustment ranges shall permit a +0dB and - 6dB variation about this point. 5) Form 731 a. The Emission Designators should be: 1M25W7D, 2M50W7D, 6M00W7D, 7M00W7D, and 8M00W7D. b. Consistent with KDB634817, page 4, Item III, only the widest bandwidth needs to be listed. 6) We provide a schematic for the transmitter, FCC-ID: I4U-25VST. This document is considered included under the confidentiality request. IMT does not have a schematic for the RF power amplifier; it is sourced from a supplier as a component, with a Specification Control Document (SCD). The provided SCD is considered IMT Confidential, and included under the confidentiality request. 7) A Bill-of-Materials (BoM) is supplied for the transmitter, again considered a confidential submission. IMT does not have a BoM for the RF power amplifier. 8) This device is intended for use only by professional/occupational users. The transmitter does not have user accessible external controls, in compliance with 90.203(g). Frequency programming tools are only provided to service/maintenance personnel. 9) I have reviewed the assembly drawing provided, and do not find the FCC Part-15 statements shown on the label. 10) The two Part-15 statements have been deleted from the user manual.

I4U-25VST-AMP Confidentiality Request.docx Created by kitkos Page 1 of 2 Confidentiality Request Pertaining to Request for Certification of FCC ID: I4U-25VST-AMP TO WHOM IT MAY CONCERN Integrated Microwave Technologies (hereafter referred to as IMT) hereby respectfully requests confidentiality of certain materials pursuant to published FCC guidelines, with respect to our Request for Certification of FCC ID: I4U- 25VST-AMP, in accordance with FCC Sections 0.459(b), and 0.457(d) IMT has submitted a Technical Report, as required by FCC guidelines, in conjunction with the Request for Certification. Certain parts of this Technical Report and/or the attendant submittals contain information that are trade secrets and are requested to be withheld from public inspection. The attachments and/or exhibits, henceforth collectively “Materials”, designated as following are requested to remain confidential: Exhibit Type File Name Schematics I4U-25VST-AMP Schematics-Rev1p0.pdf SC902-M072-02E-E5.pdf Bill of Materials BOM_900-HPVST-001-R-RevA1.pdf BOM 900-HPVST-001.pdf Amplifier SCD 690-A0030-01A-R-A.pdf Operational Description I4U-25VST-AMP Theory of Operation- Rev1p0.pdf Block Diagram I4U-25VST-AMP Block Diagram-Rev1p0.pdf Internal Photos I4U-25VST-AMP Internal Photos-Rev1p0.pdf These materials contain commercial trade secret information that would reveal our unique proprietary system design which is a result of our proprietary Research and Development. These materials comprise information that differentiates our products from those of our significant market competition, and which allow us to operate in the very competitive market for this product. These materials, if released, would result in substantial competitive harm due to unlicensed copying of our proprietary design(s) in whole or in part. Integrated Microwave Technologies 200 International Drive Mt. Olive, NJ 07828 T + 908 852 3700 F + 908 813 0399 www.imt-solutions.com IMT Nucomm RF Central I4U-25VST-AMP Confidentiality Request.docx Created by kitkos Page 2 of 2 To protect these materials, IMT does not release them to the public, and protects them from unauthorized disclosure by third parties via the execution of Non-Disclosure Agreements. In respect to the internal photo of the final Power Amplifier, IMT feels that additional justification for confidentiality exists due to the fact that the amplifier circuit board(s) are mounted inside a sealed component that can sustain damage upon opening, and that opening would nullify any equipment warranty since the equipment is only serviceable by IMT or our designated technicians. For warranty administration purposes, IMT applies stickers to the component housings that will indicate if the housing has been opened, to ensure that only designated service technicians have access. The internal images of the amplifier would provide any reasonably savvy RF engineer the means to replicate the design and result in substantial competitive harm to IMT. Also, the internal photos show the digital circuitries and IC markings, which would provide competitors information on the technologies used. Therefore, internal photos would expose our proprietary design information, would provide any reasonably savvy digital design engineer the means to replicate the design, and result in substantial competitive harm to IMT. 25VST-AMP is a microwave transmitter. It is only operated by and under the control of video transmission professionals. It is not a general consumer product, and it is not accessible by general public. IMT requests that these materials be withheld from public inspection in perpetuity due to the possibility and likelihood that the designs will be utilized, in whole or in part, by IMT as the basis for future products which would likewise be subject to the same competitor interest. Sincerely, . Stephen D. Kitko FCC Contact Person, Compliance Engineer
