The power synthesizer is particularly suitable for broadband high-power microwave circuits.
Description
Technical field
The present invention relates to microwave transmission device, more specifically, relate to a kind of microwave and millimeter wave planar broad band high power combiner.
Background technology
In microwave, millimetre-wave circuit, power combiner is widely used in the microwave and millimeter wave high power circuit.From six the seventies to stage now, emerged in large numbers lot of research about power combiner, and these achievements light be widely used in the microwave engineering technical field.The plane high power combiner of conventional is the Gysel electric bridge, but because the discontinuity of Gysel electric bridge so bandwidth is narrower, can not satisfy the requirement of Modern wireless communication for power output height, broadband far away.Thereby, high power more, more the plane high power combiner of wide bandwidth in the industry cycle receives much concern.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of microwave and millimeter wave planar broad band high power combiner is provided.Not only circuit loss is low for this power combiner, bandwidth, compact conformation, be easy to process, have good heat dissipation characteristics, is convenient to that the solid state microwave high power is synthetic to be used.
The structure of microwave and millimeter wave planar broad band high power combiner according to the invention is as shown in Figure 1, and the characteristic impedance of output port [1], input port [2,3] is identical, is made as Z
0The characteristic impedance of isolated port [4,5] is 2Z
0The resistance of isolation resistance [6,7] is Z
0The characteristic impedance of metal ring band [10] is
