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.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
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.
