Abstract
PURPOSE: To improve the reliability of a filter circuit by setting up an air-core section in which no microwave absorber exists at a part of the coil wound around the absorber.
CONSTITUTION: The microwave absorber 17 is axially shifted by l1. This permits the coil 15 to have the air-core coil 15a with a length of l1. This also enables the filter circuit impedance for the microwave to change and the filter circuit to meet the condition that it reflects the microwave from the leading terminal 7. Since the microwave to propagate the leading terminal 7 is reflected at the air-core coil 15a, both the coil 15 and the microwave absorber 17 can be prevented from gnerating heat by the microwave and the filter circuit reliability be improved.
