RF Micro Devices,
Inc.'s RFPD2650 is a gallium
nitride-based hybrid power doubler amplifier delivers low distortion
performance with the flexibility to optimize for supply current or energy
consumption. The RFPD2650 hybrid power doubler amplifier module is specifically
designed for CATV infrastructure applications including hybrid fiber coaxial
(HFC) optical nodes.
The RFPD2650 supplies a
minimum gain of 21 dB over the entire 45-1003 MHz frequency range. It can
deliver up to 20 percent power or energy savings with no performance penalty in
HFC networks, or it can be configured to provide 3dB higher distortion level
performance with the same power consumption. With this blend of performance
attributes, the RFPD2650 enables MSO system designers to select either
industry-leading or energy saving ("green") performance.
The RFPD2650 leverages GaN
HEMT and GaAs pHEMT technology to enable longer range transmission. Maximum
current is 450mA, and current consumption can be reduced dramatically to less
than 370mA for applications requiring reduced distortion performance.
Programmed to match the distortion level of competitive devices, RFMD's RFPD2650
delivers two watts of power consumption savings.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The first photos made with a 3D-printed telescope are here and they're not as fuzzy as you might expect. A team from the University of Sheffield beat NASA to the goal. The photos of the Moon were made with a reflecting telescope that cost the research team £100 to make (about $161 US).
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
