One of the main issues in microwave and wireless system design is to ensure high performance with low cost techniques. The six-port technique allows for this in critical network design areas. This practical resource offers a thorough overview of the six-port technique, from basic principles of radio frequency measurement-based...

General-purpose Test Environment For high-performance, high-speed testing of RF and microwave devices, Aeroflex introduced the SMART^E™ 5300 general-purpose test environment. The DC to 40 GHz SMART^E 5300 is unique in its ability to test, monitor and control any Device Under Test (DUT) within a single test environment. SMART^E 5300...

AR's Bargain Corner There is more than one way to get the quality equipment you need. If your budget is tight, the AR Bargain Corner is a good place to find some great values. New with MCB, discontinued and demonstration equipment is available at a fraction of its original...

Anritsu introduces demodulation analyzers for LTE, WiMAX, W-CDMA/HSDPA and legacy standards such as GSM, CDMA and EV-DO for use with its Spectrum Master™ MS2712E/MS2713E. The new capabilities make the Spectrum Master MS2712E/MS2713E the first handheld spectrum analyzers in this class to deliver these measurements, and provide field technicians and...

Engineers designing, integrating and verifying receiver signal processing components and devices today face a critical challenge. They must keep pace with the rapid design changes imposed by their industry while dealing with the ever-increasing pressure to be first-to-market. Unfortunately, evolving and unclear standards complicate this challenge, leading to design...

Printed slot antennas are currently under consideration, especially for use in ultra-wideband (UWB) applications, due to their attractive merits, such as lightweight, ease of fabrication and wide frequency bandwidth. 1 In addition, these antennas are completely planar and are easily integrated with active devices or monolithic microwave integrated circuits...

In this article, a new Doherty amplifier using high-efficiency inverse class F and class F amplifiers is presented. The characteristics of inverse class F and class F amplifiers have been analyzed for their bias conditions and load impedances in order to identify their suitability to be the carrier or...

Total markets for terahertz systems are likely to surpass $1 B per year by the end of the decade, thanks to the availability of robust, relatively inexpensive terahertz systems that are capable of addressing the most high profile applications such as security, medical imaging and process control. A new...

Exalt Communications announced that the California Department of Forestry and Fire Protection (CAL FIRE) has deployed its microwave backhaul systems to support video surveillance for unstaffed lookout towers in El Dorado County. This unique application, the largest of its kind in the United States, allows CAL FIRE dispatchers in...

All radio frequency (RF) links are subject to distortion due to the physics of the transmission media, as well as the physical environment in which the link is operating. While designers take these effects into account when developing communication systems, actual testing with these distortions realistically applied to the...
