I4U-65SKTX-71Skymaster TX HD/SD COFDM Transmitter 65SKTX

The new SkymasterTX (SKTX) is a lightweight, full-featured digital COFDM video downlink transmitter built to address the unique requirements of aircraft downlink operation. The chassis design features either horizontal or vertical ARINC mounting. All of the connections and controls have been lo- cated on one side of the unit. This allows the SkymasterTX to be removed from one aircraft and installed in another with ease. A unique feature of the SkymasterTX is a built-in GPS receiver. This allows aircraft position data to be downlinked to the command center for display on a moving map system. This feature allows rapid location of the aircraft. The SkymasterTX can operate in a wide variety of bands delivering High Definition and Standard Definition video resolutions. The SkymasterTX can output up to 8W of RF power extending and improving link reliability. The SkymasterTX features COFDM digital modulation. COFDM modulation is unaffected by multipath – unlike single-carrier modulation formats such as FM, CDL or QAM. The SkymasterTX has a built-in H.264 (MPEG-4) encoder or optional MPEG-2 encoder. MPEG-4 encoding is the latest encoding method. It requires 50% less bit-rate over MPEG-2 improving the reliability of the transmission even more. MPEG-4 also allows for the transmitting of High Definition video without sacrificing performance. IMT has taken great care with the design of the internal H.264 encoder. It has been designed with video quality as its cornerstone. The quality of the encoding rivals that of full-featured rack mounted encoders. Knowing that security of the video is critical, the SkymasterTX features the latest in AES 128 and 256 encryption. This feature can be enabled or disabled very easily allowing the mode to be selected depending on the mission requirements. To ensure interoperability between vendors we also conform to BCRYPT, a published, non-proprietary standard. The front panel LCD and a Remote Control user interface allow for quick control of preset selection, standby mode, and encryption mode. For ad- vanced functions such as changing frequency plans, AES encryption keys, or unit naming, an easy-to-use administration software package is sup- plied. Configuration is flexible with 16 or more different presets available.

I4U-65SKTX-71 Confidentiality Request-Rev1.0.docx Created by wangj Page 1 of 2 Confidentiality Request Pertaining to Request for Certification of FCC ID: I4U-65SKTX-71 TO WHOM IT MAY CONCERN Integrated Microwave Technologies (thereafter refers 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- 65SKTX-71, 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 followings are requested to remain confidential: Exhibit Type File Name Schematics I4U-65SKTX-71 Schematics-Rev1.0.pdf Operational Description I4U-65SKTX-71 Theory of Operation-Rev1.0.pdf Block Diagram I4U-65SKTX-71 Block Diagram-Rev1.0.pdf Internal Photo* I4U-65SKTX-71 Internal Photos-Rev1.0.pdf *previously approved case via KDB for same hardware approved under FCC ID I4U-65SKTX IMT is formerly known as RF Extreme, LLC, Nucomm Inc. 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 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 You’ll know us by the company we keep: IMT Nucomm RF Central Microwave Service Company I4U-65SKTX-71 Confidentiality Request-Rev1.0.docx Created by wangj 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 Agreement’s. In respect to the internal photo of the Final Power Amplifiers, 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 said component itself is mounted inside an enclosure that the end-user may not readily open, and that so opening would nullify any equipment warranty since the equipment is only serviceable by IMT or our designated technicians. 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. 65SKTX is a microwave transmitter. It is only operated by and under the control of Studio professionals. It is not a general consumer product, and it is not accessible by general public. Furthermore, the equipment is only serviceable by us, the manufacture or our trained designated technicians 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.
