Abstract

CIRCUITO DE AJUSTE PARA AJUSTAR UMA AMPLITUDE DE UM SINAL, E, MéTODO PARA AJUSTAR UMA AMPLITUDE DE UM SINAL EM UM CIRCUITO DE AJUSTE A invenção relaciona-se a um circuito de ajuste para ajustar uma amplitude de um sinal de radiofreqüência. O circuito de ajuste compreende diversos terminais para entrada e saída, um componente de casamento possuindo um efeito no casamento de uma entrada de sinal e de uma saída de sinal, para e a partir dos diversos terminais. O circuito de ajuste também inclui pelo menos uma unidade de resistência ajustável entre o componente de casamento e a terra, para mudar uma resistência da entrada e da saída de pelo menos um terminal do circuito de ajuste de amplitude. O circuito de ajuste para ajustar uma amplitude de um sinal também pode incluir diversos terminais para entrada e saída, pelo menos um par de unidades de impedância ajustável. Cada par de unidades de impedância ajustável está colocado entre um par de terminais de entrada e saída. Cada uma das unidades de impedância ajustável é acoplada em paralelo entre uma linha de sinal e a terra, e as unidades de impedância de cada par possuem reatâncias complementares ema em relação à outra.
