Phasor’s mobile communication system adopts Vicor FPA, which can provide great current under low voltage

As a leading developer of enterprise-level Electronic navigation antenna (ESA) systems for satellite mobile broadband applications, Phasor has partnered with Vicor to develop a power solution for its system that provides unprecedented connection speed and bandwidth during movement .

This technology provides reliable satellite connections for aviation, navigation, land mobile and defense applications and has made major breakthroughs. It helps end customers to participate in multi-party video conferences or watch videos and play online regardless of the mode of transportation. The music is not interrupted or dropped.

Phasor’s thin, flat or conformal solid-state electronic navigation antenna system can be built into the roof of trains and other vehicles. The antenna thickness is less than 25 mm, and its performance is comparable to a dish antenna with a width of 2.4 meters or more. Vicor FPA is slim but can provide high power density. The mobile communication system supporting Phasor can provide extremely low voltage with great current.

Mike Warren, Phasor’s senior vice president of operations, said: “Vicor is an important partner that supports technological innovation and can help us achieve product differentiation. FPA technology plays an indispensable role in our ESA, and we look forward to product commercialization. It will continue to maintain cooperation with Vicor as it transforms.”

The Vicor FPA package contains a pre-regulator module (PRM) and a transformer module (VTM)/current multiplier, which together can provide a comprehensive isolated regulated DC-DC converter function. The transformer module (VTM) is a resonant converter, so compared with hard-switching converters, the noise is also very low.

The Vicor system can convert a 48V power supply into a 1.5V power supply (1V in a new-generation antenna with higher current), which is critical to the successful operation of the Phasor antenna. Phasor hopes to achieve this conversion at a current of 65A (or even 80A), which is the main design challenge for its application-specific integrated circuit (ASIC) power supply. Compared with traditional DC-DC converters, Vicor transformer solutions can provide higher power transmission performance and efficiency without supporting multiple hard-switching converters with different phases to achieve 65A current.
