Abstract

The invention provides a high-isolation power synthesis device, and belongs to the technical field of radio frequency and microwave power synthesis design. The device is mainly composed of a power dividing unit and a power combining unit, wherein the power dividing unit is composed of a one-to-two waveguide power divider and a waveguide-microstrip dual probe, a one-to-two microstrip power divider and an SMPM connector; the power combining unit is composed of a two-in-one waveguide power combiner, a waveguide 3dB bridge and a waveguide-microstrip dual probe. The power dividers are used for power distribution, so multiple paths of equal-amplitude same-phase power flows are obtained; the power amplification is conducted through the power amplification module, and finally, the obtained powers are combined, so larger output power is obtained. The device achieves the high-power, miniaturized and high-isolation signal output of the power divider / power combiner.

Description

technical field [0001] The present application belongs to the technical field of radio frequency and microwave power synthesis design, and in particular relates to a high isolation power synthesis device. Background technique [0002] With the increasing application of microwave and millimeter wave technology in radar detection, satellite communication, electronic warfare, navigation control and other military fields, the requirements for the output power of the signal source are getting higher and higher. Only by obtaining a high enough output power, can a sufficiently good communication quality, a sufficiently far transmission distance, and a sufficiently strong anti-interference ability be ensured. However, a single solid-state power device often has limited output power and cannot meet the high-power output requirements of the system. At this time, it is necessary to combine the power of multiple solid-state device amplifiers through a specific circuit. This circuit is c...
