Abstract

"DISPOSITIVO DE DEFASAGEM DE BANDA LARGA". A presente invenção se refere a um dispositivo de defasagem de banda larga. Uma defasagem <sym> é introduzida em um oscilador local de freqüência fixa. O princípio da presente invenção é realizar uma translação dupla dos sinais de entrada. A variação de fase introduzida no nível do oscilador local tem um valor positivo em um dos sinais transladados e um valor negativo no outro. Os sinais se recombinam na freqüência de recepção com uma diferença de fase de 2 <sym> de modo a maximizar a amplitude do sinal na saída do somador.
