This invention discloses a miniaturized, highly selective bandpass filter chip for multipath transmission, comprising an input port, an output port, a port matching network, five octagonal inductors (L1~L5), seven MIM capacitors (C1~C7), and one ground inductor Ls1. It includes a conventional filtering path (Path A) and a compact coupling path (Path B) connected in parallel between the input and output ports. The port matching network is composed of capacitors C4 and C7. Path A forms three resonant units by connecting capacitors C1~C3 in parallel with inductors L1~L3, which, together with capacitor C5, inductor L4, and ground inductor Ls1, constitute a basic bandpass structure and generate low-frequency transmission zeros. Path B forms a compact coupling network by connecting symmetrically coupled inductor L5 in parallel with capacitor C6, utilizing mutual inductance coupling to generate additional high-frequency transmission zeros. The filter chip is implemented using GaAs-based IPD technology to achieve fully lumped component integration, possessing advantages such as compact structure, high selectivity, stable performance, and high integration density.

This invention relates to a look-ahead multipath routing method for low-Earth orbit (LEO) satellite networks based on node importance. The method includes: collecting data from several homogeneous satellites in the LEO network to construct an undirected graph; calculating the overall quality score of each node in the undirected graph; using the overall quality score of each node as a basis, employing a look-ahead greedy algorithm for path planning, and selecting multiple non-intersecting paths through virtual pruning and recursive look-ahead mechanisms; and triggering route recalculation or dynamic optimization of traffic allocation based on whether the initial traffic sharing weight of each non-intersecting path triggers route maintenance conditions. This method achieves deep integration and collaborative optimization of long-term link stability and global node importance, effectively overcoming the short-sightedness of traditional routing methods and significantly improving the overall performance, reliability, and adaptability of multipath transmission in dynamic LEO satellite networks.
