Base Station WiFi

Indoor Unit
Harsh environments associated with base station applications demand high efficiency, high reliability, and small footprint power converters. Vicor's IBC (Intermediate Bus Converter) modules based on patented SAC (Sine Amplitude Converter) topology provide the highest efficiency, output power, and reliability in a standard eighth-brick and quarter-brick package.

Outdoor Unit
Smaller in size, and housed in a weather-sealed enclosure, outdoor units rely on free-air cooling and are powered from either a 48 V or
24 V PoE source. Vicor's VI Chips are available in 24 V and 48 V inputs are the smallest, highest power density and efficiency converters available.

DC Converters – Isolated Fixed Ratio

  VI Brick Intermediate Bus Converter
These Intermediate Bus Converter (IBC) Modules are very efficient, low profile, isolated, fixed ratio converters for power system applications in enterprise and optical access networks. Rated at up to 850 W, these IBCs conform to industry standard eighth and quarter-brick footprints. The greatly increased power cabability often allows the eighth brick to replace a conventional quarter brick, while the quarter bricks can replace two or more conventional quarter bricks. Their leading efficiency enables full power operation at 65°C with as little as 400LFM airflow. Their small cross section facilitates unimpeded airflow — above and below the thin body — to minimize the temperature rise of downstream components.


A Sine Amplitude Converter that offers superior performance, the highest efficiency, and highest power density in the smallest package available. BCMs provide an isolated intermediate bus voltage to power non-isolated PoL (Point-of-Load) converters or serve as an isolated voltage source for ATE, server, telecom, and industrial control applications.

DC-DC Filters – Input

  QPI Family
The Picor QuietPower QPI family of active EMI filters provides conducted common-mode (CM) and differential-mode (DM) attenation from 150 kHz to 30 MHz (CISPR22 range). The proprietary active filtering circuit provides superior attenuation at low frequencies intended to support EN Class B limits, including PICMG 3.0 for ATCA boards. In comparison to passive solutions, the use of active filtering reduces the volume of the common-mode choke, providing a low-profile, surface-mount device. Smaller size saves valuable board real estate and the reduced height enhances airflow in blade applications.


The FIAM family of front-end modules provides EMI filtering, transient protection, and inrush current limiting in DC-DC applications, in a half-brick sized package. The 48 V
FIAM enables designers using Vicor's 48 Vin Maxi, Mini and Micro series DC-DC converters to meet the transient immunity and EMI requirements of Bellcore, FCC, ETSI, and European Norms. The Transportation/Railway FIAM modules (FIAM072 and FIAM110) are DC front-end modules designed for rail applications providing transient protection, inrush current limiting and EMI filtering.
