After Chinook Downing, RPG Defeat Should Get More Priority

It was very sad to hear about the recent downing of the Chinook helicopter in Afghanistan that killed 38 soldiers. Eastern Afghanistan has steep mountain ranges, providing shelter for militants with rocket-propelled grenade launchers creating a dangerous area for military aircraft and personnel. Large, slow-moving air transports like the CH-47 Chinook are particularly vulnerable, so the military should not be surprised that one was shot down especially if it is not equipped with countermeasures as it is a relatively defenseless aircraft. The two greatest dangers faced in asymmetric warfare are improvised explosive devices (IED) and rock propelled grenades (RPG)...

The Mine Clearing Beast Autonomous Vehicle

Wireless controlled autonomous vehicles of all kinds are being developed by the military. An interesting type being developed are IED and mine clearing vehicles. They can safely clear areas for the military and civilians caught in war tore areas. The Digger D-3 is a mine-clearing robot with a unique approach. Instead of poking around to locate mines and explosives, it shreds that area and eats them. It is a land tiller on steroids (and lots of them). At the front of the D-3 is a giant spinning metal pulverizer, which has tungsten hammers that beat down a quarter meter into...

Is RF Radiation from Cell Phones Dangerous?

A very controversial subject is whether RF radiation from cell phones is dangerous to our health. There are studies showing that it might be and others that show is not dangerous. Many people do not realize that RF radiation at these frequencies is non-ionizing so it cannot damage the cell structure on the molecular level like solar radiation does. However, it can heat the cells (as a microwave oven does to food) but cell phones are relatively low power so does it do any damage to us? Nothing conclusive to date has shown that it is dangerous at the...

New Ga Tech Device Captures Ambient EM Energy to Drive Small Electronic Devices

This was published from Ga Tech a week or so ago - interesting research on energy scavenging: Researchers have discovered a way to capture and harness energy transmitted by such sources as radio and television transmitters, cell phone networks and satellite communications systems. By scavenging this ambient energy from the air around us, the technique could provide a new way to power networks of wireless sensors, microprocessors and communications chips. Georgia Tech School of Electrical and Computer Engineering professor Manos Tentzeris displays an inkjet -printed rectifying antenna used to convert microwave energy to DC power. This grid was printed...

ABI Research Teardown: Samsung Galaxy S II Shows Interesting RF Design-ins

I received this ABI Research promo today and found some interesting RF findings in the Samsung Galaxy S II, a new flagship member of Samsung's Android smartphone lineup. As part of its new Teardown Research Service, ABI Research has dismantled, analyzed, and tested the device down to the component level. If you are looking to keep up with the latest technology in 2011, the Galaxy S II is a good place to start. According to ABI Research vice president of engineering James Mielke, “Samsung started from scratch with this phone: almost every component is new. Its application processor is...

High Capacity MM-Wave Coms: A Mid-Year Checkup

Wireless Technology Expert Jonathan Wells reports that at mid-2011 the high capacity wireless market segment continues to grow in strength. All the carriers are now advertising 4G networks and claiming super-fast download speeds. High-capacity gigabit wireless products are being deployed in both the microwave and mm-wave frequency bands to address the backhaul demands of these networks. Over 1 million microwave radios in 2010 Although 2010 saw a drop in overall PTP radio shipments, high capacity solutions remains the shining sector. EJL Wireless reports that of the almost 1.1 million PTP radios shipped last year, 75% of them are in...

Interesting Products at IMS2011

After crusing around the inner harbor (aka the exhibition floor) for three days, here is a quick rundown of some interesting products we came across: - Agilent's integrated vector signal generator up to 44 GHz and analog signal generator up to 67 GHz (operational to 70 GHz), and the first microwave analog signal generator to break the 1 W output power barrier. - Anritsu introduced a new broadband VNA system that provides single-sweep coverage from 70 kHz to 110 GHz with operation from 40 kHz to 125 GHz, and utilizes an advanced design that eliminates the need for large, heavy...

IMS2011 First Impressions

The Baltimore inner harbor area is a beautiful setting for the IMS2011 and certainly convenient for us on the east coast. The sessions are in full swing with some very interesting topics being presented. I see trends in very high efficiency amplifiers with better modeling/measurement techniques, new packaging techniques from LCP to fusion bonded laminates, very wideband active devices to cover multiple frequency bands, highly integrated modules that solve co-existence problems, new signal generators that provide real life signal replication and storage and more. The exhibition is very lively and positive - attendance looks very good this year. The...

Heading Off to IMS2011 in Baltimore

The "dance card" is full (actually overflowing) and the pre -show coverage, articles, May show issue and Online Show Daily are ready. Our Online Show Daily page will be updated each day (or even more often) with the latest news items and features a real-time Twitter Feed, blog updates, exclusive show articles and chair message plus will have pictures and videos just following the show. The biggest surprise leading up the show for me was all the acquisitions ( Skyworks acquired SiGe and Advanced Analogic Tech plus NI acquired AWR and Phase Matrix). In addition, the abundance of news items...
