Abstract

The invention allows for improved accuracy and simplified tuning. In the fcoio .3.lf; f segment of a rectangular waveguide (OPV) I, a metal disk 5 is placed parallel to its walls. A semiconductor diode 2 is inserted between it and one of the wide walls of the OPV. Due to the introduction of a metal ring 6 mounted on the edge the metal disk 5, and the movement of its perpendicularly wide walls of the OPV 1, allows the fine tuning of the semiconductor diode 2 to the microwave oscillations excited in the OPV 1. 1 il.

Description

one

The invention relates to radio electronics and can be used to optimize the parameters of a microwave device.

The purpose of the invention is to increase accuracy and simplify tuning.

The drawing shows schematically the proposed microwave node settings, a longitudinal section.

The microwave tuning unit contains a segment 1 of a straight-line | waveguide, a semiconductor diode 2, one electrode 3 of which is fixed on the wide wall of a segment 1 of a rectangular waveguide, and a metal disk 5, a tall ring 6, is attached to another electrode 4.

The microwave tuning unit works as follows: in a similar way.

; In segment 1, a microwave oscillation is excited. By moving the metal ring 6 perpendicular to the wide walls of the segment 1, the capacitance between the metal rings changes.
