Abstract

In the field of power synthesis, the present invention proposes a compact four-way power distribution and synthesis structure, including a straight waveguide, a microstrip probe, an impedance matching section, a Wilkinson bridge, and an isolation resistor, and the straight waveguide is the input port of the power divider and the output port of the synthesizer, two symmetrical substrates are arranged at a quarter wavelength away from the short-circuit surface of the straight waveguide, and opposite microstrip probes for signal coupling are fixedly installed on the substrates, and each microstrip probe The strip probes are matched and connected to the microstrip line through the corresponding impedance matching section, and the microstrip line corresponds to the cascaded Wilkinson bridge; the impedance matching section, microstrip line, and Wilkinson bridge are all installed on the substrate The present invention has the characteristics of small size, compact structure, low loss, high port isolation, wide bandwidth, etc., and also has the function of four-way power distribution/combination from waveguide to microstrip transition; it can be applied to radar, electronic countermeasures, Electronic communication and other fields, suitable for microwave and millimeter wave frequency bands.

Description

technical field [0001] The invention relates to a microwave and millimeter wave power distribution and synthesis structure in the field of electronic communication. It is a compact four-dimensional structure that also completes the transition from waveguide to microstrip while solving the problem of small size structure, high isolation, low loss, and high synthesis efficiency. Road power distribution and synthesis structure. Background technique [0002] In microwave and millimeter wave passive and active circuits, power dividers and combiners are widely used in various system components. In recent years, various systems including space-borne missiles have put forward higher and higher requirements for small-size components; in microwave and millimeter-wave active circuits, integrated circuits have the advantages of small size and high integration; in high-power In the application, the waveguide has more advantages in terms of high power capacity and low loss; in the field ...
