Abstract

"TRANSCEPTOR UTILIZANDO UM MISTURADOR DE REJEIçãO HARMÈNICA". A presente invenção descreve um transceptor sem fio que inclui um transmissor que possui um misturador de rejeição harmónica e um loop travado em fase de saída RF em uma arquitetura de conversão para transmissão de duas etapas, e um receptor de conversão direta. O transmissor inclui um oscilador local para produzir um sinal em um múltiplo de uma freq³ência intermediária, um misturador de rejeição harmónica de modulador em quadratura responsivo ao sinal no múltiplo da freq³ência intermediária para modular sinais de banda base em fase e em quadratura de fase para produzir um sinal de freq³ência intermediária, um sinal comutável responsivo ao sinal de freq³ência intermediária para produzir um sinal de freq³ência intermediária filtrado e um loop de fase travada deslocada de saída de RF responsiva ao sinal de freq³ência intermediária filtrado e ao sinal no múltiplo da freq³ência intermediária para produzir um sinal de transmissão de RF. O misturador de rejeição harmónica reduz as exigências de filtragem para facilitar um nível alto de integração de circuito enquanto o loop travado em fase deslocada de saída reduz o consumo de potência. A comutabilidade do filtro permite a utilização do transceptor para comunicação EGSM, DCS e PCS. O oscilador local pode usar um inteiro ou loop de fase travada de N fracionário.
