Stealth Microwave introduced the SM1822-44, a GaAs FET amplifier designed for high-performance military and commercial markets. The unit operates from 1800 to 2200 MHz with a P1dB of 44 dBm across the band and an OIP3 of 55 +dBm, typical. Small signal gain is 45 dB with a flatness of ±.5 dB across the band. Standard features include a thermal protection with auto reset, over/reverse voltage protection, TTL on/off, FWD and REV power detection and level control.
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.
