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.
The company says it anticipates high-definition video for home security and other uses will be the next mature technology integrated into the IoT domain, hence the introduction of its MatrixCam devkit.
Siemens and Georgia Institute of Technology are partnering to address limitations in the current additive manufacturing design-to-production chain in an applied research project as part of the federally backed America Makes program.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
