Abstract

"ESTAçãO RADIOTRANSCEPTORA" Uma estação radiotransceptora evita os problemas de dispositivos anteriores que tanto não usa antenas de multi-feixe ou amplificadores de potência de multi-portadora, permitindo sinais de vários transceptores serem seletivamente dirigidos a um lóbulo de antena com baixa perda. A estação radiotransceptora inclui um sistema de antena que tem uma pluralidade de feixes, uma pluralidade de transmissores de rádio, cada transmissor de rádio incluindo uma parte de banda base e uma parte de radiofreq³ência que tem uma amplificador de potência de radiofreq³ência de portadora única, uma pluralidade de filtros que são conectados respectivamente à pluralidade de transmissores de rádio e que são sintonizáveis a sinais de portadora respectivos gerados por transmissores de rádio respectivos, e uma matriz de comutador para conectar os selecionados dos filtros ao sistema de antena tal que sinais de portadora gerados pelos transmissores e amplificados pelos amplificadores de potência de radiofreq³ência de portadora única podem ser irradiados por feixes selecionados. Cada transmissor pode ser conectado independentemente a cada feixe de antena de cada outro transmissor.
