C+A 1 C+A TRANSCEIVER INSTALLATION GUIDE ____________________________________________________ The installation of California Amplifier products should only be attempted by qualified personnel, and should be under the direct guidelines of the system operator. These installation instructions apply to California Amplifier products only. Use of these instructions to install other manufacturer’s products may result in unknown hazards, damage and/or unacceptable performance. The information contained in this applications note is intended to assist the operator in developing a set of installation guidelines and operating practices for the field personnel skilled in installing roof top subscriber equipment. California Amplifier accepts no responsibility for claims of injury, death, destruction of property or loss of television service related to improper installation, or installation of equipment by staff not skilled in installing roof top cable television equipment. 460 Calle San Pablo, Camarillo, California 93012 USA PH: (805) 987-9000 Fax (805) 987-8359 C+A 2 GENERAL INSTALLATION INSTRUCTIONS FOR MDS-MMDS TRANSCEIVER NOTE to System Operator: The AirStream Transceiver has been designed for installation by a licensed or qualified installer with experience in installing wireless antennas. NOTE to Installer: The authority to operate this device requires its operation and installation, including antennas, to comply with the FCC-adopted radio frequency (RF) exposure limits. It is in the responsibility of the installer to install this device and associated antennas so that RF exposures to people do not exceed 1.0mW/cm 2 . The power output near of this transceiver at the antenna exceeds the FCC adopted RF exposure limits for people. When used with an antenna with a maximum gain of 17 dBi the exposure limit is satisfied if the antenna is at least 30 centimeters or 12 inches away from all people. INSTALLATION PRACTICES In a customer installation, there are several factors that must be considered before the installation can take place: Signal contour strength and direction of the transmitting source, seasonal interference’s such as foliage and trees, aesthetics of the outdoor installation, system performance and overall customer satisfaction with the final product. In each case the customer wants the very best signal quality with a minimum of construction and aesthetic impact to their home or business. This will dictate the use of a variety of antenna configurations in order to perform the task of providing adequate signal strength while maintaining low visual impact. The order of visual impact follows the height and size of the antenna. A wall or gutter mount will present a very low visual profile. This if followed by a short roof or chimney mount. When higher gain or foliage clearance is needed, then a tree mount or mast mount should be considered. The following mounts are described and their general application: Wall or Standoff Mount: These are used in high signal density areas where antenna aesthetics is of concern. It offers great flexibility in mounting angles and locations. The stand-off arms mount from the wall and or the eave and support the mast in the vertical position. The mast may be short in length so as to place the antenna above the roof C+A 3 line or a telescoping mast may be used in conjunction with a ground plate to extend the antenna height to above the roof peak. Roof Mounts: The same basic hardware used for wall and eave mounts is used for a roof mount. This mounting bracket and pole is adjustable in the vertical plane and will raise the antenna about 24” above the mounting location. The bracket must be secured into a structural member, not simply into siding or shingles. All points of attachment must be properly waterproofed. Chimney Mounts: Chimney mounts are one of the easiest types of mounts to install. In the application of brick-type chimneys, a dual band strap mount is best. The proper strap will securely fasten the mounting bracket and antenna. For wood over metal construction chimney, a version of the wall mount is best. Make sure the anchor bolts attach to a supporting stud member and not just the fascia board. C+A 4 Tripod Mount: The tripod mount offers ease of installation, stable mounting structure, and signal visibility. It is however, bulky and not very aesthetic. The tripod mount comes in 3, 5, 10 and 15-foot sections. As with the roof mount installation, the mounting bolts must always be attached to roof joists and be properly sealed. Tree Mounts: In regions of the country with heavy foliage, tree mounts are popular. This is a highly specialized installation and is beyond the scope of this installation guide. Specific instructions and practices can only be formatted by the individual operator in their region (not pictured). Every installation must adhere to company policies, applicable specifications and drawings of the system operator. This requirement includes: the choice of antennas, the weatherproofing of all connections, all penetrations into the building and all grounding procedures, both at the antenna mount and at the point of drop entry into the building. C+A 5 INSTALLATION PLANNING In addition to meeting the highest standards of quality and workmanship, another valid goal is to minimize the amount of time spent on a customer’s property, thus minimizing any disruption of a customer’s schedule. Good planning helps an installer to be efficient and productive on each installation. Site Survey Although the general receive location may have been previously surveyed by a signal crew, a detailed, on-site survey is usually required prior to beginning an install. During this survey, signal readings must be recorded on the installation work order. The exact components that were used as well as the mast height should be noted at this time. You should also create a simple drawing of the antenna installation, including structural supports and ground system relative to…

MDS-MMDS Transceiver 520005-1 Description Of Operation This product is a two-way microwave transceiver designed to operate over the MDS band (2150- 2162 MHz) as the transmitter and over the MMDS band (2500-2686 MHz) as the receiver. The receive and transmit chains of the design are combined utilizing proper dilpexing and filtering at each respective band. There is one common RF port for both RF Receive (Rx) band, and RF Transmit (Tx) band, and one common IF port for the Rx IF band and Tx IF band. This product is designed to operate with cable-ready type Modems in order to provide high speed internet access to the consumers. Modem upstream IF band is 14.375-26.375 MHz and downstream IF band is 222-408 MHz. As an out door unit, this transceiver is connected to a directive Antenna, which is designed to cover both Rx and Tx bands. The Antenna gain of a typical installation is about 17 dBi. The transmit section in this transceiver is a dual conversion frequency translator. The modem IF input frequency band of 14.375-26.375 MHz is unconverted to an intermediate IF frequency of 116 to 128 MHz, which then gets unconverted to the desired RF transmit band of 2150-2162 MHz. The unit is capable of up to 25 dBm output 1-dB compression point at approximately 22 dB of total gain. The local oscillator (LO) used in this design is an S-Band oscillator at 2278 MHz phase locked to a highly stable Temperature Compensated Crystal Oscillator (TCXO) and exhibits a long term stability of ±10 KHz over the operating temperature range of –30 deg C to +70 deg. C. This LO is used in the second upconversion process, which yields the Tx RF band. The 142.375 MHz LO used in the first upconversion process is derived from the 2278 MHz S-Band LO by dividing it by 16. The Transmit block diagram is shown below. It shows the various gain, mixing, and filtering blocks that make up this chain. All filters were specifically designed and placed appropriately along the transmit chain to achieve the desired rejection masks in order to comply with internal and external interfering sources and emission requirements. A QPSK signal of up to 6 MHz wide within the frequency band of 14.375-26.375 MHz is provided from the Hybrid Networks modem, model number N231. The output is adjusted in 1 dB steps from 8 dBmV to 58 dBmV into the transceiver, which in turn gets up converted twice for the desired RF transmit band of 2150-2162 MHz. In order to eliminate aggregate noise power at the receive hub due to emitted broad band noise from all the subscribers connected to the service, and thus maintain adequate signal quality, the transceiver utilizes a blanking feature which allows it to turn off the Transmitter when not in use. The transmitter is enabled by a predetermined minimum signal received from the modem. A typical install at a subscriber’s site includes this modem, the transceiver, the antenna, a plug-in power supply, cables and any additional powers dividers/splitters. The installer mounts the transceiver with the Antenna at a rooftop, and aligns the antenna towards the service provider’s hub for maximum signal quality. A cable run connects the transceiver with the indoor modem. This establishes the link between the transceiver and the hub. Sufficient link budget margin should be allowed to maintain link between the subscriber’s site and the service provider’s hub. -22 dB Integrated MDS/MMDS Transceiver Block Diagram (520005-1) (Transmit/Upstream) To Downconv.
