Abstract

"CONTROLE PERDAS DE DE OSCILADOR LOCAL EM PROCESSOS DE CONVERSãO DIRETA". Trata-se de um sistema e um método para gerar uma freq³ência de oscilador local (LO) em um receptor ou transmissor de freq³ência intermediária (IF) . Um sinal é recebido de um oscilador controlado por tensão (VCO) . O sinal tem uma freq³ência de VCO. A freq³ência de Vco é dividida por um número N para se produzir um sinal com uma freq³ência dividida. o sinal possuindo a freq³ência de VCO é então misturado com o sinal possuindo a freq³ência dividida (divided-down), para se produzir um sinal de saída com uma freq³ência de saída. A dispersão do oscilador local é reduzida. Deste modo, o receptor ou transmissor pode operar em multi-banda e modos de comunicação sem fio e atender às especificações afins.
