Abstract

The project consists of developing and constructing an electronic component called a Hybrid Amplifier Module (MHA). This component is used inside amplifiers used in Cable TV (CATV) Systems and Collective VHF/UHF and “C” Band Systems. Another important application is its use in TwoWay amplifiers using two communication channels. These amplifiers enable amplification of TV signals in one direction and data amplification, making possible Home Banking, Home Shopping and Internet services in broadband networks in CATV systems. The first phase will be to undertake the electrical design project for an amplifier in the push-pull and cascode configurations, in order to obtain a circuit with broadband characteristics (40- 860MHz), high gain (34dB), a low noise ratio (<8dB), low distortion, solid construction, high reliability and a high degree of repeatability for largescale production. To succeed, the components will have to be modeled to optimize the circuit and the simulations. In this stage, Proqualit will be helped by the CPqD - Telecommunications Research and Development Foundation’s laboratory. The 2nd phase consists of the manufacturing of the prototypes employing alumina layers coated with metal through a Cooper Plating process. This stage will also involve the milling of the steel bases on which the layers will be deposited, as will the covering. The encapsulation will have to be to world standard SOT115J2. The third stage provides for the establishment, development and the design project for setting up the testing of the component. Finally, in the 4th stage, the qualification testing will be carried out. (AU)
