Sunnyvale, Calif. - Two silicon germanium HBT amplifiers from Stanford Microdevices Inc. are optimized for the 800- to 1,000-MHz and 1,900- to 2,400-MHz communication bands, and designed for use in second- and third-generation wireless infrastructure and fixed-wireless applications. The SGL-0163 has a noise figure of 1.2 dB, a 5-dBm-input third-order intercept point and a small-signal gain of 16 dB. In lots of 10,000, it's priced at 50 cents each. The SGL-0263 has a noise figure of 1.3 dB, a 6-dBm-input third-order intercept point and a small-signal gain of 15 dB. It's priced at 95 cents. Both MMIC devices come in SOT-363 plastic packages.
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.
