HIGH-FREQUENCY COMPOSITE SWITCH COMPONENT

摘要

A small high-performance high-frequency composite switch component having a reduced number of diodes. The switch component has first to forth ports. A diode is connected between the first and second ports. A first transmission line of lambda g/4 ( lambda g is the wavelength of the frequency in a first frequency band) and a substantially open first element which is a substantially simple reactance component in a second frequency band are connected in series between the second and third ports. A second transmission line of lambda d/4 ( lambda d is the wavelength of the frequency in the second frequency band) and a substantially open second element which is a substantially simple reactance component in the first frequency band are connected in series between the second and third ports.
