By Mark Forbes, Mentor Graphics Corporation As is well known, maximum RF coupling occurs when impedances on each side of the coupling match. A perfect match occurs when the impedances are identical and the Complex Matching Factor (CMF) is 0dB. When the CMF is 0db, the imaginary terms of the complex conjugate cancel, and the resistance is equal.
"Logic Analyzer in a Day" Engineering Challenge - Using FPGA Module and Front Panel Software Development KitJune 4, 2010 8:00 am | Product Releases | Comments
Opal Kelly, a leading producer of powerful USB-based FPGA modules that provide essential device-to-computer interconnect, today announced the "Logic Analyzer in a Day" Experts’ Challenge, using an Opal Kelly module and its integrated FrontPanel Software Development Kit (SDK).

After three years of deliberation, the IEEE802.16m air interface definition will be ready for prime time in the next few months. This critical step toward creating true 4G cellular technology based on WiMAX is important enough to earn compliant products a new name: WiMAX 2. Further proof came last month, when an impressive subset of the WiMAX community created the WiMAX 2 Collaboration Initiative to "improve the economics of mobile broadband" and "to create a better value chain for service providers.
Freescale Semiconductor has introduced its MSC8155 digital signal processor (DSP), a higher performance and cost-optimized version of the company's flagship MSC8156 DSP based on the latest StarCore technology. The MSC8155 includes next-generation acceleration and interconnect technologies that boost overall chip performance and further enhance the capabilities of broadband wireless base station equipment.

Virtual System Prototypes (VSPs) offer a means to develop and debug embedded software before the silicon is available. By Jeff Roane, VaST Systems Technology Corp. As the semiconductor industry continues to consolidate off-the-shelf hardware components to build wireless consumer devices, such as 3G phones, these devices are increasingly differentiated by software content....LISTED UNDER: Software, Development
Berkeley Varitronics Systems' Swarm tablet PC software operates on indoor and outdoor Wi-Fi site surverys. The program combines Yellowjacket® 802.11b/a/n/g Wi-Fi receiver measurements with GPS geo-coding accuracy. The software enables survey bitmap creation, scanning for all 802.11b/a/n/g channels with automatic correlation, and exporting of data including RSSI, MAC and SSID....LISTED UNDER: Services, Calibration / Test | Software, Test
The security and privacy we have come to trust (primarily through wired networks) has quickly been disappearing, resulting in the requirement for a new form of network connection security. Wireless Ethernet tackled this problem not once, but twice. The second attempt, so far, looks to put an end to security problems “in-the-air” for Wi-Fi.
Analog Devices, Inc. announces the release of ADIsimPLL Version 3.0, a new generation of its phase-locked loop (PLL) circuit design and evaluation tool, as well as two PLL synthesizers delivering desirable performance for the upconversion and downconversion of RF signals in wireless base station equipment....LISTED UNDER: Software, Design
