Telecom Lead India: AEG Power Solutions says its solutions improve base station performance for 4G/LTE deployments.
The company’s new eighth-brick CME02, designed for RF power amplifiers, complements its CMH12 half-brick and the CMF21 and CMF25 full-brick products.
These products’ features also support competitive marketplace for 4G/LTE wireless base stations as operators deploy new infrastructure to keep pace with consumer demand.
Shipments of 4G-capable smartphones are expected to grow by more than 400 percent in 2013, says IDC’s Asia/Pacific Quarterly Mobile Phone Tracker.
Earlier this year, Maxis became the first operator in Malaysia to launch LTE / 4G services, which it claims is capable of providing up to 5 to 10 times faster download speeds than its 3G data services, while other operators such as Celcom and DiGi have announced their intentions to rollout LTE plans in 2013.
IDC expects competition in the 4G space to intensify and demand for LTE-enabled smartphones to significantly increase towards the second half of 2013, when LTE networks from all three major mobile operators are expected to be up and running.
AEG Power Solutions says 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.
In addition, 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 percent 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.
