Apple iPhone charged up by Ascent Solar CIGS power
The solar firm has broken into a new market. It intends to provide its CIGS modules in other chargers for other smart phones, including the latest Samsung Galaxy, very soon
Ascent Solar, a developer of flexible thin-film photovoltaic modules, has launched a charger for the Apple iPhone 4/4S smart phone.
RFHA1006
Using an advanced high power density GaN semiconductor process, RFMD says these high- performance amplifiers achieve high efficiency, flat gain, and a large instantaneous bandwidth in a single amplifier module.
The device is suited to class AB operation for public mobile radio and can provide a PA stage for commercial wireless infrastructure. It can also be employed in general purpose Tx amplification, test instrumentation and in civilian and military radar applications.
This GaN transistor is packaged in an air cavity ceramic package for excellent thermal stability through the use of advanced heat sink and power dissipation technologies.
Ease of integration is accomplished through the incorporation of optimised input matching network within the package that provides wideband gain and power performance in a single amplifier. An external output match offers the flexibility of further optimizing power and efficiency for any sub-band within the overall bandwidth.
With an output power of 9W,the device employs advanced heat-sink technology and has a 225MHz to 1215MHz instantaneous bandwidth. It is input Internally matched to 50Ω, typically operates at 28V and has an output power of 39.5dBm. The module also has a gain of16dB and power added efficiency of 60% and works in the temperature range -40°C to 85°C Large signal models are also available.
Branded under Ascent’s new “EnerPlex” line of consumer products, the charger incorporates the company’s ultra light CIGS solar cells in a sleek, protective iPhone 4/4S case, along with a thin battery. Ascent says the charger adds minimal weight and size to an iPhone smart phone, yet provides significantly improved battery life by harnessing sunlight for electric power.
Enerplex charger powered by CIGS technology
This is the first product in a forthcoming line of smart phone chargers from Ascent. The company also plans to introduce similar chargers for other smart phones, including the newly launched Samsung Galaxy S III, in the near future.
Ascent Solar’s President and CEO, Victor Lee, comments, “The EnerPlex charger is the first protective iPhone case to leverage the lightweight qualities and superior aesthetics of our CIGS solar technology. It will extend the usage time of iPhone smart phones while preserving the high level of design quality that consumers demand. Apple customers can now incorporate green technology into their everyday life, improving the performance of their smart phone without compromising style.”
