Vicor FPA Improves Reliability of Mobile Satellite Broadband Connectivity
Increased efficiency for video playback and music streaming on the move via Pager ESA
Provides DC/DC converter and noise reduction in combination with PRM·VTM

A mobile communication environment is established that delivers high current at low voltage, ensuring uninterrupted connection speed and bandwidth even while on the move.
Vicor announced that it can improve the reliability of mobile satellite broadband connectivity by using Factorized Power Architecture (FPA).

Vicor developed a new power solution through collaboration with Phasor, a provider of enterprise-grade electronically scanned antenna (ESA) systems for satellite-based mobile broadband applications.

This technology not only provides reliable satellite connectivity for air, maritime, terrestrial mobile, and defense applications but also enables end users to seamlessly utilize multi-connection video conferencing, video playback, and music streaming even while on the move.

Phaser's low-profile, flat, conformal solid-state electronic scanning antenna system can be installed on the roofs of transportation vehicles such as trains, and spans over 2.4m despite being less than 25mm thick. It has performance comparable to a dish antenna of that size.

In addition, the mobile communication system of the phaser, which uses low-profile components to operate at high power density, provides high current even at low voltage through Vicor's FPA.

The Vicor FPA package combines a pre-regulator module (PRM), a voltage conversion module (VTM), and a current multiplier to provide comprehensive isolated DC/DC converter functionality. The voltage conversion module (VTM) is a resonant converter, offering very low noise compared to hard-switching converters.

In particular, using Vicor's system, 48V voltage can be converted to 1.5V voltage, and compared to conventional DC/DC converters, the efficiency of power supply is increased, eliminating the need to use multiple hard-switching converters with different phases to achieve 65A.
