Abstract: A directional coupler includes a primary transmission line electrically coupled in series between an input port and an output port of the coupler, and an asymmetric, meander-shaped, secondary transmission line, which is electrically coupled in series between a coupling port and an isolation port of the coupler. The secondary transmission line includes a first coupling segment, which is reactively coupled to a first portion of the primary transmission line, and a second coupling segment, which is reactively coupled to a second portion of the primary transmission line, and is spaced closer to, or farther from, the primary transmission line relative to the first coupling segment, such that an asymmetry in reactive coupling is present between the first and second portions of the primary transmission line and the secondary transmission line. An intermediate segment is provided, which is electrically coupled in series between the first and second coupling segments.

Abstract: Computer-implemented methods, apparatus, and systems for data storage and data query are described. During data storage, the number of neighboring graph nodes in each starting graph node in directed graph graph data to be stored is determined, and a data storage mode is determined according to the number of neighboring graph nodes. When the data storage mode is not an ultra-large node data storage, node data, neighbor information, outgoing edge index feature information, and outgoing edge data of the starting graph node are stored in the same data fragment. When the data storage mode is an ultra-large node data storage, node data, neighbor information, outgoing edge index feature range information, and outgoing edge data are stored in a starting graph node data fragment, and the outgoing edge data and outgoing edge data storage address information of the starting graph node are stored in at least two outgoing edge data fragments.

Abstract: Relation network data query includes receiving a query request for an edge using a first node as a starting node, where the edge satisfies a specified filter condition comprising that the edge has a first edge data item and a corresponding first data value. Multiple index blocks associated with the first node are obtained from a non-volatile storage storing a relation network. A first index block corresponding to the first edge data item is determined from the multiple index blocks based on a correspondence between an index block and an edge data item, where the first index block comprises multiple data values of the first edge data item and location information of edges having the multiple data values and using the first node as starting nodes. Location information of an edge having the corresponding first data value is determined from the first index block and the edge obtained.
