Abstract
Patente de Invenção: <B>"CIRCUITO TRANSFORMADOR DE BANDA LARGA COM TAXA DE ALTA IMPEDâNCIA"<D>. Um circuito transformador descrito executa a transformação (acoplamento) da impedância de faixa ampla e pode ser usado para aplicações de elevação e diminuição de tensão. O circuito descrito é composto de dois transformadores de lina de transmissão (T1, T2) e duas impedâncias reativas (Z1, Z2) que compensam o circuito pela impedância versus frequência. O circuito descrito executa uma taxa de impedância real de faixa ampla de 1:9. O circuito pode ter taxas de voltas diferentes para T1 e T2 e valores diferentes para Z1, Z2 para acomodar valores de transformação racionais, fracionais e inteiros até uma taxa de impedância de 16:1. A adição de um balun na saída produz uma saída equilibrada.
