Abstract

"DISPOSITIVO COMBINADOR DE SINAL, E, PROCESSO PARA RECEBER E TRANSMITIR SINAIS USANDO UM RáDIO MULTIBANDA". Um dispositivo combinador de sinal e processo permite a uma unidade novel usar uma antena única para receber e transmitir informação em duas ou mais faixas de freq³ência. O dispositivo combinador inclui primeiro e segundo circuitos de transmissão e primeiro e segundo circuitos de recepção, que são conectados a um dispositivo de "casamento". O dispositivo de "casamento", por sua vez, é conectado à antena. O primeiro circuito de transmissão e o primeiro circuito de recepção são projetados para transmitir e receber, respectivamente, um sinal digital, e o segundo circuito de transmissão e o segundo circuito de recepção são projetados para transmitir e receber, respectivamente, um sinal analógico ou um sinal digital. Usando o dispositivo combinador de sinal é possível combinar sinais de diferentes bandas de freq³ências, especialmente sinais digitais e sinais analógicos de faixas de freq³ências diferentes. Como tal, a presente invenção permite o uso de uma antena comum em um rádio de modo dual. A invenção encontra uso exemplar em um sistema de rádio comunicações móveis celulares e/ou um sistema de rádio comunicação via satélite.
