USA: AEG Power Solutions announced the availability of its new eighth-brick CME02, completing the range of board-mount power products designed specifically for RF power amplifiers.
The CME02 complements the CMH12 half-brick and the CMF21 and CMF25 full-brick products already available from AEG PS. All of these products incorporate features that support the very competitive marketplace for 4G/LTE wireless base stations as operators deploy new infrastructure to keep pace with consumer demand.
These products provide voltage regulation using a high performance control loop that responds extremely quickly and can fully stabilize the output voltage within less than 300µs even after a load transient of 50 percent. The output voltage can be trimmed over a wide range to precisely match the RF amplifier needs and optimize RF performance.
The trim input also allows the voltage to be reduced during periods of low traffic to further improve overall system efficiency. These products are suitable for use in a sealed enclosure mounted on the antenna tower and feature a built-in baseplate for conduction cooling, allowing full power delivery at up to 100°C. The efficiency is greater than 91% which minimizes excess heat in the enclosure and an optimized single-board design offers a highly reliable solution.
The full brick and half brick products are ideal for macro BTS and remote radio head applications, where they provide clean DC power at up to 700W from either 48V or 24V input. Industry trends are toward smaller cell sites to provide improved coverage in urban areas, using combinations of micro BTS, pico cells and similar small systems.
There is a corresponding demand for high performance RF amplifiers with lower RF output levels and the CME02 is designed for these types of applications, with up to 80W dc power from 48V input.
In addition to this range of standard products, AEG PS manufactures a large number of custom and semi-custom solutions for RF or other specific applications, operating from either AC or DC input. By leveraging from existing product platforms, AEG PS can develop custom solutions that offer the lowest system cost while delivering outstanding performance and reliability.
