DELAY-LINE STRUCTURE OF SPIRAL TYPE

摘要

FIELD: electricity. ^ SUBSTANCE: delay-line structure of spiral type contains metal frame with at least one spiral located at ends of dielectric supports. At least one metal ring with grooves with rigidly fixed free ends of dielectric supports is installed at frame concentrically in regard to spiral; the ring has possibility of translational movement along the system axis. At the ring there is also a tool for ring translation in the form of protrusion with threaded hole for connection with pin which ends are installed at grooves of housing flanges. In result of pins rotation metal rings are translated with spirals along longitudinal axis of delay-line structure. During spirals movement distance between them is changed and it leads to changes in operating frequency and delay coefficient of the structure. It allows adjustment of delay-line structure. ^ EFFECT: provision of structure adjustment. ^ 2 cl, 1 dwg
