IEC 60728-3-1:2012 is applicable to the methods of non-linearity measurement for cable networks which carry only digitally modulated television signals, sound signals and signals for interactive services. These methods take into account the specific signal form and behavior of digitally modulated signals which differ from the analogue broadcast signals represented mainly by the … [Read more...]
Silicon ESD Protection Diodes for High Brightness and Power LED Markets
OnChip Devices has introduced miniature, wire bondable, silicon ESD protection diodes targeted for High Brightness and Power LED markets. The ESD7979 and ESD9595 diodes are designed with a junction, which enables conduction of high transient currents. These zeners exhibit no device degradation when compared to Multilayer Varistors (MLV). All devices meet the requirements of … [Read more...]
Multiple TVS Arrays for Lightning and ESD Protection
ProTek Devices introduced multiple transient voltage suppressor (TVS) arrays featuring a variety of configurations ideal for embedded transient voltage protection for applications such as Ethernet, USB, smartphones, and other portable electronics. ProTek's TVS Arrays product line provides protection from transients caused by Electrostatic Discharge (ESD), Electrical Fast … [Read more...]
Updated Test Mobile Platform for LTE Development
Aeroflex Limited announced that it has added support for enhanced Inter Cell Interference Cancellation (eICIC) to the TM500 Test Mobile platform. Functionality for testing carrier aggregation was added to the platform earlier this year. eICIC is an enhanced inter-cell interference coordination technique specifically designed to improve the overall performance of HetNet … [Read more...]
Lightning Damage Costs Double for Electronics
The cost of insurance claims for lightning strikes nearly doubled between 2004 and 2011, and insured losses reached $1 billion last year alone according to a study by the Insurance Information Institute. The National Lightning Detection Network recorded nearly 23.4 million lightning flashes nationwide in 2011, but the rising cost isn’t entirely to do with the weather. In fact, … [Read more...]
Electronic Engineer Confesses He Never Earned Degree in His Own Obituary
Val Patterson, 59, an electronic engineer from Salt Lake City, died of throat cancer July 10. He wrote his own obituary last fall, using the piece to confess to some actions he made in life: stealing a safe and not earning his Ph.D. The obituary was published in the Salt Lake Tribune. Patterson calls himself "a true scientist," and describes his upbringing and … [Read more...]
Laser Generates More Energy than the Entire United States
The National Ignition Facility, home to the world’s largest laser, pulled the trigger on 192 beams of optically amplified, electromagnetic radiation-emitting light – all fired within a few trillionths of a second of each other, to deliver 500 trillion watts of "peak power" and 1.85 megajoules of ultraviolet laser light. This amount of power is greater than what the entire U.S. … [Read more...]
The EMC Community Perspective
As indicated in a previous blog post, it seems hard to justify the rationale behind testing medical equipment for RF immunity at 3m distance. It is this greater test distance (as opposed to the 1m test distance accepted in automotive and MIL-STD testing) that is driving the high price of the replacement amplifiers. A change from the current test field strength of 10v/m @ 3m to … [Read more...]
Two new connector lines in push-on family announced at IMS conference
Carlisle Interconnect Technologies announces the availability of two new connector lines to its push-on family – the TMP and WMP series, at the IMS conference held in Montreal, Canada. The TMP family is designed to provide higher power handling capacity, similar to an SMA connector, for use in radar and other high power RF and microwave systems. The TMP interface enables … [Read more...]
