A compact four-way power distribution Composite Structure

The present invention is in the field of synthesis of power, presents a compact four-way power distribution synthesis structure, including straight waveguide, microstrip, impedance matching section, Wilkinson bridge, isolation resistance, the straight waveguide splitter input port and a combiner output port, disposed at a distance shorter pavement fourth straight waveguide wavelength 100min substrate, there is fixedly mounted on the microstrip substrate relative to the signal coupling, each micro with the probe through the impedance matching section connected to the microstrip line, microstrip line and then the corresponding cascaded Wilkinson bridge corresponding; the impedance matching section, microstrip line, Wilkinson bridge are mounted on a substrate ; the present invention has a small size, compact structure, low loss, high isolation port, wide bandwidth and other characteristics, but also has a waveguide to microstrip transition to four-way power divider / combiner functions; can be applied with radar, electronic warfare, electronic communications and other fields, each suitable for microwave and millimeter wave frequencies.
