RELAY DEVICE AND IC TESTER USING IT

摘要

PROBLEM TO BE SOLVED: To provide a relay device with a favorable high frequency characteristic and an IC tester using it by using an inexpensive relay.;SOLUTION: This invention is improved on a relay device passing a signal including a high frequency component through a relay. It is characterized by that it is provided with a printed circuit board connected with a conductive plane and the relay and provided with a strip line or a microstrip line having a particular impedance to the conductive plane, and a conductive plate attached to the printed circuit board in a neighborhood of a signal path of a relay interior and electrically connected with the conductive plane.;COPYRIGHT: (C)2003,JPO
