Description

(54) STROBOSCOPIC CONVERTER

The invention relates to radio engineering and can be used in phase metering, in the measurement of low power voltages and microwave parameters.

A stroboscopic converter is known that contains a segment of a rectangular waveguide with a diode with an accumulation of charge and two mixing diodes placed in it, which are connected to the input by means of a symmetrical strip line 1.

However, in such a transducer, a characteristic pedestal arises before the strobe pulse, which is the result of gating the pulse front by a parasitic surge following the strobe pulse.

The purpose of the invention is to improve the shape of the strobe pulses.

To do this, in a stroboscopic converter containing a segment of a rectangular waveguide with a charge-accumulating diode and two mixing diodes connected to the input using a single-line strip line inside a segment of a rectangular waveguide on one of its wide walls between the mixing diodes and a charge-accumulating diode is additionally placed a dielectric resonator, for example, an ellipsoidal shape.

In the drawing, the construction of a stroboscopic converter is given.

The stroboscopic converter contains a segment of 1 rectangular waveguide,

5 diode 2 with charge accumulation; mixing diodes 3, 4; symmetric strip line 5; dielectric resonator 6; capacitance 7.

The converter works as follows.

“Way.

Strobe pulses are formed using a diode 2 embedded between the upper and lower walls of segment 1, forming a two-wire line. The voltage drops formed by diode 2 propagate to the side walls and, reflecting from them, contribute to the creation of short pulses between the middle points of the horizontal walls of the segment 1. Strobe pulses are fed to the mixing diodes 3 and at the same time the signal under study is fed through a symmetric strip line. In diodes 3, 4, discrete signal spectrum conversion is performed using short strobe pulses.
