Multilayer Organic (MLO) technology for RF/wireless components in multiband applications

July 30, 2013 11:43 am | by George White, PhD, and Michael Ulrich, AVX Corporation, www.avxcorp.com | Comments

Today, low-temperature co-fired ceramic (LTCC), multilayer ceramic (MLC) and ceramic mono-block technologies are the dominant choices for the implementation of surface mount components for RF passive filters, diplexers, baluns and front end modules. LTCC is the most popular ceramic technology since it uses miniature lumped components....

Solve high power consumption challenges in active RFID systems

July 30, 2013 11:12 am | by Shawn Rezaei, ams, www.ams.com | Comments

Active RFID usually operates at 455 MHz, 850 MHz, 900 MHz, 2.4 GHz or 5.8 GHz. It is suited to applications such as asset and people tracking, access control, passive keyless entry in cars, parking management systems and temperature monitoring. Active RFID tags have greater transmission power than passive tags.

MEMS Innovations in Semiconductor Testing

July 25, 2013 2:02 pm | by David Schroll, Field Applications Engineer andJeff Rumowski, Assistant Manager – Test & Measurement market Omron Electronic Components LLC | Comments

In the semiconductor industry, precision testing is key to ensuring proper functionality and quality.  Two types of testing are traditionally performed: 1) wafer testing 2) chip set testing Both types of tests require the use of relays with fast switching speed to carry various types of signals.  Test boards are designed with as few as two relays or as many as several thousand per board.

The truth about test and measurement

July 16, 2013 2:41 pm | by M. Simon, Technical Contributor | Comments

Test and measurement starts with standards. You have to have standards for mass, distance, charge, and time (plus a few others) so all standards refer back to those fundamental unit standards. But you don't measure volts in units of amps, kilograms, meters, and seconds, that requires something more convenient (i.e. measuring volts in volts).

Select the right power system to optimize availability and efficiency needs

July 16, 2013 10:34 am | by Peter Panfil, Emerson Network Power, www.emersonnetworkpower.com | Comments

When it comes to power system design, there are many options to consider that affect efficiency, availability and scalability. In most cases availability and scalability are the primary considerations for data centers. The data center is directly dependent on the critical power system, and electrical disturbances can have disastrous consequences....

Non-contact infrared temp sensors monitor heat sinks and pipes

July 15, 2013 9:13 am | by Vasco Polyzoev, Systems Engineer, Texas Instruments | Texas Instruments | Comments

Measuring temperatures using infrared (IR) sensors without direct contact with an object, is the new paradigm in optimizing thermal monitoring and control. In this article we introduce the idea of this approach by taking advantage of new and very small IR temperature sensors available on the market.

The role of sensors in stable HVAC systems: Heavy duty pressure transducers

July 15, 2013 9:05 am | by Ketan Mehta, Honeywell | Honeywell Sensing And Control | Comments

Whether it’s a high-rise office tower or a manufacturing floor, Heating, Ventilation and Air Conditioning (HVAC) systems are designed for building occupants’ comfort. When systems operate at optimum levels, they’re energy efficient and go unnoticed. When they’re not, efficiency drops and complaints rise.

The government has been helping itself to our personal data all along

July 11, 2013 5:03 pm | by Chris Warner, Executive Editor | Comments

In the last few months I’ve been writing about various efforts of the government – both on the local and federal level – to leverage our consumer technologies to learn about our driving habits, cellular records, and, in the event of cyber attack, access to email records. Taken in totality, one could be highly suspicious that virtually anything and everything about our lives is accessible....

A tale of two cities: Ethernet meets PCIe

July 10, 2013 4:28 pm | by Michael Zimmerman, vice president of marketing, Tilera Corporation | Comments

Two industry megatrends are reshaping the way we design and deploy networks and compute (i.e. datacenter servers). The first is Network Functions Virtualization (NFV) with the goal of moving functions such as content distribution, firewalls and base station controllers from proprietary hardware to standard, low cost servers.

Self-healing circuits: A living immune system for ICs

July 10, 2013 4:08 pm | by Kasey Panetta, Managing Editor | Comments

One of the challenges of working with integrated circuits is as designers try to make ICs faster, the transistors become smaller and can’t handle as much voltage and the amount of variation grows. Plus, a single fault in the IC could mean a useless chip, bringing projects and products to sudden jarring halt.
