AVX has developed an 0603 case size
surface mount capacitor capable of supporting frequencies from 700 MHz
to well above 5 GHz. Designated the MLOC Series, the advanced organic RF
capacitors maintain high Q and high self-resonance while providing low
ESR values at high frequencies.
The capacitors, based on AVX's patented multilayer low loss
organic (MLO) technology, are polymer-based organic capacitors that use
high-conductivity copper interconnects in a multilayer fashion. The
ability to fabricate these components on large area substrates with
sophisticated laser direct imaging allows for improved cost benefits and
tolerance control. The end result is a low profile, low ESR and
high-performance RF capacitor.
In addition, the MLOC Series is expansion
matched to printed circuit boards to allow for improved reliability.
The RoHS-compliant RF capacitors are 50 VDC to 250 VDC rated with
capacitance values ranging from 0.1 pF to 2.5 pF with capacitance
tolerance to ± 0.02 pF. Available in 0603 case size with a 100% tin
finish, the MLOC Series features stable NPO characteristics with an
operating temperature range of -55 to +125°C. The MLOC Series surface
mount capacitors are well suited for use in RF power and low noise
amplifiers, filter networks, and MRI systems.
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.
