【Abstract】 This paper presents the design of a miniaturized power dividing and amplifying module suitable for the L-band. The module achieves six-way signal distribution through a cascaded one-to-two power divider,combined with low-noise amplifiers, filters, and switching circuits, thereby fulfilling the functions of power division and amplification for antenna-received signals while optimizing radio frequency(RF) performance.Through processes such as design specification analysis, component selection, and simulation calculations, the architectural design of the module was determined. The design adopts a multi-layer PCB layout and a hybrid process architecture, with the upper layer utilizing bare-chip microassembly technology to achieve high-density integration, and the lower layer employing surface-mount devices to reduce manufacturing complexity. Test results demonstrate that all performance metrics meet the design requirements. By integrating structural layering and process fusion, the module achieves high isolation characteristics within a compact space.更多还原
