Title:
RESISTANCE ATTENUATOR
Document Type and Number:
Japanese Patent JPH08154005
Kind Code:
A
Abstract:
PURPOSE: To provide a satisfactory reflection characteristic of the resistance attenuator to be used for a circuit module to which frequency bands over a wide range are requested.
CONSTITUTION: Microstrip lines 231-23n-1 and resistors 241-24n are alternately connected between transmission lines 22a and 22b so as to position the resistors 241 and 24n at both the sides of terminals. Then, the resistant values of the resistors 241 and 24n are set so that the normalized impedance is equal to unity.
