<p>A unit for processing radio-frequency signals received via satellite, first converted to a first intermediate frequency (I.F.), and filtered, amplified, converted, demodulated and processed by the unit itself, for obtaining standard TV audio and video signals; the aforementioned unit being formed using microcomponents facing in parallel manner and welded to the conducting tracks on a printed circuit. Such a technique provides, among other things, for reducing the overall size of the unit, and for reducing electromagnetic interference between the circuit blocks and the unit itself.</p> |
