Abstract

The present invention is applicable to the technical field of wireless communication, and provides a directional coupler and a manufacturing method thereof. The directional coupler includes a first microstrip line, a first insulating medium, a second microstrip line and a second insulating medium, The first insulating medium includes a first top surface and a first bottom surface, the first microstrip line and the second microstrip line are helical, and are respectively arranged on the first top surface and the first bottom surface , the second insulating medium includes a second top surface and a second bottom surface, and the second top surface is fixedly connected to the first bottom surface. The invention can realize the miniaturization of the directional coupler and meet the volume requirement of the directional coupler in the technical field of wireless communication.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a directional coupler and a manufacturing method thereof. Background technique [0002] The directional coupler is a directional power coupling device, which can continuously sample the transmission power along a certain direction of the transmission line, and can divide an input signal into two equal amplitude and 90° phase difference. Signal, mainly used for multi-signal combination, improve the utilization rate of the output signal, can be applied to high-power circuits in the field of wireless communication, the directional coupler packaged on the printed circuit board is used in electronic warfare, communication and radar systems Indispensable element. [0003] In the prior art, the volume of the directional coupler is large, and it is difficult to meet the miniaturization requirement of the directional coupler in the technical field of wireless c...
