The New Face of Hardware in the Loop
By Justin Panzer, Business Development Manager, Tektronix |
The extraordinary complexity of smartphones, tablets, and other wireless-enabled products coupled with new product “sell-by” dates measured in months can make design, testing, and verification a formidable challenge at best.

 In Defense of DARPA; Lamenting Bell Labs
By Barry Manz
A federal agency like DARPA is a sitting duck for politicians and assorted other critics. It has come up with some truly bizarre programs over years that ultimately either delivered no tangible results, were canceled before they could cause any damage, or attempted to answer questions that nobody was asking or needed answers to.

 Low Loss 4x2 Hybrid Diplexer
The new CM-20 is an integrated 4x2 hybrid multi-band combiner with a unique design that combines two low band signals within 698 to 960 MHz with two high band signals within 1710 to 2170 MHz. It is ideal for low PIM head end DAS applications.
MICROLAB
 Coaxial Bandpass Filter
ZX75BP-1940+ is a wideband bandpass filter in a rugged connectorized package covering 1710 to 2170 MHz. It is designed for asymmetric rejection applications such as super-heterodyne receivers. Features include fast roll-off on the upper sideband, good matching and low loss in the pass band, and consistent performance over temperature.

By Robin Irwin, Aeroflex Limited
There is continual pressure in the mobile terminal device manufacturing industry to reduce production costs and maximize throughput and yield. Test time is a significant element of this, and test engineers are always seeking new ways to achieve these goals.
•
By Richard Overdorf, Agilent Technologies
Wireless applications continue to expand and evolve at a pace that challenges the test resources of the engineers who are making it all possible. The rapid changes in end-user equipment and industry standards also pose serious challenges to test-equipment manufacturers.

By Walt Strickler, Anritsu Company
Advances in radar systems are requiring greater precision in test solutions to measure narrower pulse widths, as well as to examine intra-pulse behavior with finer resolution. This includes achieving a closer look at rise/fall edge effects or the profile within a pulse compression signal.
•
By Ronen Cohen, Product Manager, CTS Electronic Components
Demand for information (data, video and voice) through wireless devices such as smartphones, tablets, and mobile computers is projected to grow ten times by 2017. As demand for information increases, bandwidth and capacity are becoming more limited in an already congested spectrum. In this congested environment, RF filters’ performance plays a key role in limiting interference to improve the overall system capacity.

By Peter Walters, Chief Operating Officer, Dali Wireless, Inc.
The introduction of high-speed data services delivered via LTE or HSPA+ marked the first time that wireless operators could provide data rates high enough for video streaming and other bandwidth-intensive services. Along with this sea change came the need to maintain these data rates virtually anywhere the service was offered.

Re-certifying test equipment, such as RF power sensors, can be tedious and difficult to perform manually. In addition, it is not uncommon for power sensors to have connector wear or damage during long periods of use. It is critical to ensure the accuracy and repeatability of your calibrated power sensors. Sending power sensors out for re-certification can be time-consuming and potentially slow production testing.

By Karen Hoppe, Editor, Microwave Product Digest
It has been a while since I’ve seen this level of excitement over new technology for wireless broadband. The recent PCIA Wireless Infrastructure Show began with a pre-conference event, HetNet Express, which featured three sessions delving into DAS, small cells, and more.
