SU374547A1 - DEVICE FOR MEASURING THE TRANSMITTING POWER OF UHF - Google Patents

Description

one

The invention relates to a technique of measuring ultra-high frequencies (UHF).

Rope type devices for measuring microwave power are known, in which the microwave power is determined by the magnitude of the force acting on the K0 | rot | casing piston at 6QQBo, M1 the shoulder of the T-shaped Bolodnaya compound.

The purpose of the invention is to increase the sensitivity and reduce the dependency of the own CWS from the power input.

This is achieved by the additional introduction of two series-connected VCs: Irkul tori, to whose free shoulders through transitions from the rectangular section of the waveguide to. The round one is connected to a movable contactless shorting ring, installed in a circular waveguide.

The drawing shows a diagram of the proposed device.

The shoulder of a C-circus torus / is included in the waveguide path from the generator, and the shoulder of a b circulator / cKv Yuchen is a 2-second waveguide paradix. The shoulder in the F-circulator / is connected to the shoulder of the Y-circulator 3. The Ple-cho of the U-circulator 3 is included in the waveguide Tipa.KiT on the load side, and in the shoulder of the U-circulator 3 is included. waveguide

4 transition from a rectangular waveguide with a HIQ wave to a circular waveguide with a Yao wave. Smooth waves; water transitions 2 and 4 are connected between themselves by a segment of a circular waveguide in which they are placed; a moving short-circuit device 5, mechanically connected with a mechatronic pressure sensor 6. A mechanotrochny sensor is connected to the indicator 7.

The falling power passes from the shoulder a to the hull of the B-circulator 1, is reflected from the short-circuiting hole 5, passes from the shoulder b to the shoulder into the U-circulator /, then from the shoulder g to the shoulder of the Y-circulator 3 and enters to load. The reflected power passes from the shoulder d to the shoulder of a Y-circulator 3, is reflected from the short-circuiting 5, passes from the shoulder e to the shoulder of a U-circulator 3, then from the shoulder to the shoulder of a U-aperture. At the same time, a moving short-circuiting gap on the one hand (from left to right according to the scheme) is acted upon by a force, proportional to the falling power, and on the other hand, (force to the left according to the scheme) is acted upon by the force proportional to the reflected power. The resultant force is proportional to the transmitted power. Under the action of this force, the short-circuit valve moves, resulting in the appearance of an electrical signal at the output of the mechanical sensor 6. The electrical signal from the mechatronic a-chick is measured by indicator 7, scaled in units of power (watts).

A contactless movable orthopolate piston is placed in a circular waveguide with a HOI wave, thereby eliminating the connection between the channels of the incident and reflected power through the gap between the walls of the Bolo water and the shorting port.
