Compound Semiconductor magazine has awarded RFMD for its PowerSmart power platforms. These devices feature an RF configurable power which deliver multiband, multi-mode coverage of all cellular communications modulation schemes up to 4G LTE 64QAM.
Compound semiconductor lasers and memories for making data communications greener, green laser pointers for picoprojectors and more advanced GaAs chips for tomorrow’s smart phones were all discussed at CS Europe.
Scientists can now precisely synthesise nanocrystalline materials by systematically tuning their quantum confining behaviour by using semiconductor quantum dots. This development shows potential in the optoelectronics sector including LEDs, lasers, telecoms and detection applications.
Finisar will use Ignis’ laser in its Gbps tunable 300-pin and tunable XFP product lines. It estimates that the combined worldwide market for these products will be approximately USD $250 million in calendar 2011 and will grow to approximately USD $400 million in 2015.
Strategy Analytics latest report “Battery Life and Ease of Use Most Important Factors for New Phone Buyers,” assesses the importance of 18 high-level factors that cellphone consumers consider when purchasing.
Both GaN on silicon devices have many times superior switching performance compared to similar state-of-the-art silicon-based power MOSFETs. Both devices also have low on resistance and are smaller than silicon devices with similar resistance.
