Skyworks introduced two miniature 0402 varactor diodes for voltage controlled oscillator (VCO), phase noise, and voltage-tuned filter applications. Optimized for small form factor, these discrete solutions are available in plastic surface mount technology (SMT) packages that fit the 0402 PCB footprint and are well suited for applications requiring low resistance, low inductance, and a wide tuning range.
The SMV1705-040LF and SMV1232-040LF are designed for 3V platforms in low phase noise VCOs used at frequencies in wireless systems up to and beyond 2.5 GHz. These general market diodes are also targeted at WLAN, CATV, LNB, energy management, wireless infrastructure and military markets.
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.
