RF Micro Devices Inc.'s RF724x power amplifiers
support ultra-high peak efficiency of 48-51 percent and is comprised of five
PAs covering WCDMA bands 1, 2, 4, 5 and 8, addressing common 3G/4G frequency
bands and band combinations. All RF724x power amplifiers are packaged in a 3x3
mm footprint, improving smartphone platform flexibility and ease of
implementation. RFMD's RF724x power amplifiers also feature an integrated high
directivity coupler, standard 2-bit GPIO control logic and low insertion phase
shift between bias states.
When combined with one of
RFMD's companion dc-dc converters or with chipsets featuring on-chip dc-dc
converter functionality, RFMD's RF724x power amplifiers can deliver DG.09
performance as low as 13 mA - directly translating into 3G talk time.
In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
