Abstract
CIRCUITO RECEPTOR E DISPOSITIVO DE COMUNICAÇÃO. É descrito um exemplo de um circuito receptor. O circuito receptor compreende uma entrada para receber um sinal de frequência de rádio, uma saída para prover um sinal de saída do circuito receptor, um trajeto de recebimento, em que o trajeto de recebimento é conectado entre a entrada e a saída do circuito receptor, e um trajeto de retorno, em que uma entrada do trajeto de retorno é conectada à saída do circuito receptor. O circuito receptor também compreende um transformador, em que um sinal de saída do trajeto de retorno é combinado com o sinal de frequência de rádio recebido no trajeto de recebimento para formar um primeiro sinal. O trajeto de recebimento compreende um primeiro misturador para converter de modo descendente de o primeiro sinal por uma frequência de oscilador local, e um amplificador para amplificar o primeiro sinal convertido de modo descendente. O trajeto de retorno compreende um segundo misturador para converter de modo ascendente um sinal no trajeto de retorno pela dita frequência de oscilador local. A combinação do sinal de saída do trajeto de retorno com o sinal de frequência de rádio recebido é alcançada por meio do transformador.
