 Keeping the Right Perspective on Timing
By E.L. Fox, Jr.
Fox Electronics
Discussions about technology have the power to clarify or the power to confuse, depending on the perspective they take. And when you overlay business desires for smaller, more powerful, more economical, and more energy-efficient components, it becomes even easier to overlook the underlying physics behind technology options.

LightSquared:
The Show’s Over
…Or Should Be
By Barry Manz
There are a lot of very technically astute people at the Federal Communications Commission. Many have decades of experience at every level of RF and microwave technology. How then might LightSquared’s proposal for a satellite/terrestrial LTE network have ever gotten past its first hurdle? Even a cursory inspection of the plan, in which the company's network would operate extremely close to GPS frequencies at L-band, makes interference to GPS devices almost a certainty. Read More...

MISSION
Microwave Product Digest is the premier new product magazine devoted to information on components, equipment and subsystems for the RF, microwave and wireless industries. Each issue provides news, data and applications information that engineers and engineering managers working in commercial or military markets can use to develop their products.
TWENTY-PLUS YEARS OF EXCELLENCE
Microwave Product Digest made its debut in 1989, bringing “a trade show in print” to our readers every month. Through the past two decades, we’ve become a respected source of the latest product introductions, along with solid feature articles.
WWW.MPDIGEST.COM
Our easy-to-navigate website provides new product information, industry news, opinion pieces, and in-depth articles. Each issue is posted monthly, with products and articles archived, creating a virtual encyclopedia of pertinent data. Our Supplements, another source of information, are added to the site as they are published, and are archived as well.
CIRCULATION
MPD is a BPA audited publication. Approximately 32,000 engineers tasked with design, test and applications of RF and microwave systems and subsystems read MPD in print every month. Internationally, an additional 2,400 engineers receive MPD in digital format. Our targeted engineering community is primarily involved in wireless, defense electronics, and other high frequency projects, both in the commercial and military markets.
READER RESPONSE
MPD’s tabloid-size format is simply the best for impact advertising. Your ad, when run as a full tabloid-size page, is 40% larger than a standard-size ad. Other advantages of this format is the option of wrapping your products around a standard-size version of your ad for even greater effect – and each product is assigned a reader information number that provides readers with an easy path to an advertiser’s website.
