Abstract

PURPOSE:To assure the requried amount of unmatched attenuation in a given band, by constituting LPF of no loss and no reflection within a given band in the form using the inductance of in-case lead, and adding it before and after the constant resistive type circuit network. CONSTITUTION:To the inductances la, lb of in-case lead, insufficient inductances la', lb' are added externally, and capacitors c1-c4 are added to the inside and outside the case K, allowing to constitute the 3rd order LPF circuit. The design impedance of LPF is matched to the impedance of the constant resistive circuit network. As LPF, substantially no loss, less in the loss within the pass band, is required, and the cut-off frequency is selected and unmatched specified frequency or slightly more.
