Description
Technical field
The invention belongs to electronics, communication and automatic control technology field, particularly a kind of double ridge waveguide directional coupler.
Background technology
Along with world structure constantly changes, electronic countermeasures, fields such as investigation increasingly competitive.To occupy one seat in these fields, must transform existing narrow-band devices, exploitation rapidly inversion frequency, avoid interference or realize the ultra-wideband devices of frequency hopping tracking.Existing ultra-wideband devices mainly adopts the cross coupler, and its frequency range is narrower, can not reach whole double ridged waveguide bandwidth; Directivity is poor, can not satisfy measurement requirement.
Summary of the invention
The objective of the invention is in order to overcome the defective that existing ultra-wideband devices frequency range is narrower, can not reach whole double ridged waveguide bandwidth, directivity difference, invent the double ridge waveguide directional coupler that a kind of two ridge couplers that utilize the different degrees of coupling are taken a sample to the ultra broadband high-power signal.
For achieving the above object, the present invention has taked following technical scheme:
Described double ridge waveguide directional coupler by main waveguide, complementary wave lead, end cap, absorbing load, coupling, ring flange form; The two ends of main waveguide are connected with ring flange, and main waveguide is led with screw with complementary wave and is connected, and is provided with absorbing load in complementary wave is led, and the end that complementary wave is led is provided with end cap, and the other end that complementary wave is led is provided with coupling; Offer a plurality of coupling apertures on the surface that complementary wave is led.
Described main waveguide and flange are that integral body processes.
Described absorbing load is to lead bonding with glue and complementary wave.
It is to be connected with coupling with screw that described complementary wave is led.
Good effect of the present invention is as follows: the coupling aperture on the double ridge waveguide directional coupler, changed on the ridge waveguide coupling aperture calculated factor of arranging, the degree of coupling flatness of design is reached ± 1.5, directivity 〉=30dB; Integral processing is adopted in the processing of coupler, has guaranteed machining accuracy effectively, prevents that the index that causes because of factors such as distortion from changing.

Described main waveguide 1 is that integral body processes with flange 6.
Described absorbing load 4 be lead with glue and complementary wave 2 bonding.
It is to be connected with coupling 5 with screw that described complementary wave leads 2.
Correlated performance of the present invention is as follows:
Frequency range: 0.84～40GHz
Directivity: 〉=30dB;
