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.
When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
Traditional dev kits are based on a manufacturer’s microcontroller, radio module, or sensor device. The idea is to aid the design engineer in developing his or her own IoT prototype as quickly as possible. A not-so-traditional IoT development kit released by Bosch aims to simplify IoT prototyping even further.
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.
