At the IMS2011 show earlier this month I met with a group of folks from Skyworks Solutions, Inc. who told me about the first in a series of ultra low current, general purpose low noise amplifiers (LNAs) for diverse wireless applications including satellite receiver set-top boxes, Bluetooth® headsets, medically-prescribed hearing aids, advanced meter reading devices and 2.4 GHz wireless local area networks. The aim of these parts is to deliver enhanced receiver sensitivity and wide dynamic ranges to bring about improved signal reception, increased design flexibility and reduced part counts.
Specifically, the SKY67014-396LF is an advanced gallium arsenide pseudomorphic high electron mobility transistor (pHEMT) enhancement mode process LNA with an integrated active bias and on-die stability structures enabling simple external matching and stable performance over temperature.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
