F 3 - 1 Line Extender LPAP-550 FOR PRICES SEE PRICE SHEET
The LPAP-550 is a professional quality, line extender, designed for outdoor use in an RF distribution systems. These line extenders provide distribution amplification in the 47 to 550 MHz frequency range. The LPAP-550 utilizes the lowest distortion output power addition hybrid modules available, ensuring for high output levels with very low distortion. In addition, the interstage loss is minimized thereby reducing input hybrid distortion. Low loss diplex filters and test points are used to minimize the loss on the output side of the output hybrid. Standard vernier controls for slope and gain are also available. The LPAP-550 employs built-in (hard-wired) reverse diplex filters to handle the 5 to 30 MHz return band. Areturn amp modules is available for those applications needing return path amplification. Optional plug-in attenuators, cable equalizers, and thermal compensators are also available.
The LPAP-550 is housed in a rugged, die cast housing. Test ports are accessible via the housing cover for fast verification of operating levels. Surge protection is provided via standard surge plug-in modules.
