Study of DC supply for 5G millimeter-wave front-end module

This article presents the design and experiment of a multi-output DC supply for a 5G millimeter-wave front-end module, with some specified requirements, such as miniaturization of power supply modules, wide voltage input (15-24V), multiple voltage outputs (12V, 5V, 2.5V, 1.2V), and high output current (3A). Based on the DC/DC convert LTM4634 and LT3083 for cost control, a completed the power module is designed and fabricated, along with some key information, such as the design introduction of the power supply module, structural framework, hardware design block diagram, PCB layout diagram, measurement setup, and the experimental results.
